To determine the reaction order from concentration and time data, one can use the method of initial rates. By comparing the initial rates of the reaction at different concentrations of reactants, the reaction order can be determined based on how the rate changes with respect to the concentration of each reactant.

How can one determine the order of reaction from a given table of data?
To determine the order of reaction from a given table of data, you can look at how the rate of the reaction changes with the concentration of the reactants. If the rate is directly proportional to the concentration of a reactant, the reaction is first order with respect to that reactant. If the rate is proportional to the square of the concentration, the reaction is second order. By analyzing the data and observing how the rate changes with different concentrations, you can determine the order of the reaction.
How can one determine the order of reaction by utilizing concentration and time data?
To determine the order of reaction using concentration and time data, one can plot the natural logarithm of the concentration of the reactant against time. The slope of the resulting graph will indicate the order of the reaction. If the slope is constant, the reaction is first order; if the slope doubles, the reaction is second order; and if the slope triples, the reaction is third order.
How can one determine the reaction order from a table of experimental data?
To determine the reaction order from a table of experimental data, you can plot the concentration of the reactant versus time for each experiment. The reaction order is determined by the slope of the line on the graph. If the slope is constant, the reaction is first order. If the slope doubles, the reaction is second order. If the slope triples, the reaction is third order.
The decomposition reaction of ammonia gas on platinum surface has a rate constant k equals 2.510-4 mol l-1s-1 what is the order of the reaction?
The rate constant is not indicative of the order of the reaction. To determine the order of the reaction, experimental data (such as concentration vs. rate data) is needed. The order of the reaction can be found by examining how changes in reactant concentrations affect the rate of the reaction.
How is order of reaction determined graphically?
in our syllabus there is only the first and the zero order reaction in which if the graph is plotted between the concentration and time then it is a zero order reaction while if the graph is between the log of concentration and time then the reaction is of the first order.hope this will help u.

What is stoichiometry insufficient to determine rate of a reaction?
Stoichiometry provides information about the quantities of reactants and products in a reaction, but it does not provide information about the speed at which the reaction occurs. The rate of a reaction is influenced by factors like temperature, concentration, and presence of catalysts, which are not directly determined by stoichiometry. Therefore, additional experimental data and kinetic studies are needed to determine the rate of a reaction.
What does your data indicate about the optimum substrate concentration for this lactase catalyzed reaction?
The data indicates that the optimum substrate concentration for the lactase-catalyzed reaction is typically at a concentration where the enzyme active sites are mostly saturated with substrate molecules, leading to maximum reaction rate. Beyond this point, increasing substrate concentration may not significantly increase the reaction rate due to enzyme saturation. This optimum concentration ensures efficient enzyme-substrate binding and catalytic activity.
How do you calculate the rate of a chemical reaction?
The rate of a chemical reaction is typically calculated by measuring the change in concentration of a reactant or product over time. This can be determined by plotting a graph of concentration against time and calculating the slope to find the rate. Alternatively, you can use the rate equation derived from the experimental data to determine the rate constant.
What of the following is necessary to determine the rateof the reaction using the rate law?
To determine the rate of the reaction using the rate law, you need the rate equation that relates the rate to the concentrations of reactants. It is also essential to have experimental data, such as the initial rates of reaction at different concentrations of reactants, to determine the rate constant and the order of the reaction with respect to each reactant.
How can one determine the rate law from a chemical equation?
To determine the rate law from a chemical equation, one can conduct experiments to measure how the rate of the reaction changes with different concentrations of reactants. By analyzing the experimental data, one can determine the order of each reactant and the overall rate law of the reaction.
Why is the stoichiometry of a reaction generally not sufficient to determine reaction order?
Stoichiometry only tells us the molar ratios of reactants and products in a balanced chemical equation, not the rate at which the reaction occurs. Reaction order is determined experimentally and can depend on factors such as reactant concentrations, temperature, and presence of catalysts. The rate law equation, which includes reaction order, is derived from experimental data and not solely from the stoichiometry of the reaction.
The value of k in a rate law?
K is known as the rate coefficient, or the rate constant. The value of k is particular, and varies from reaction to reaction. It is dependent on different factors such as temperature, pressure, concentration, solvent, presence of a catalyst, etc., and therefore a change in any of these gives you a new value for k. To determine the value of k, you must use the experimental data to determine if you have a zeroth order, first order, or second order reaction. As indicated by the equation below, you must also have the actual rate.Rate= k[A]m[B]n[C]pYour overall reaction order is given by the sum of the orders of reactant.If you have a zeroth order reaction overall, then k will be equal to the rate. So if the reactants are consumed at a rate of 1.00 mol/liter/sec, then your k has a value of 1.00 mol/liter/sec. This means that no matter how much of the species you add, a lot or just enough, you will not change the rate.If you have a first order reaction where the concentration of A, [A] (in mols/liter), is consumed at a rate of .004 mol/liter/sec, then k = [A]/.004 mol/liter/sec, as given by the above equation: You divide the rate by the concentrations of the reactants. The units for a first order reaction are sec-1 or 1/sec, because you are dividing moles per liter by moles per liter per second. So the concentration of this does matter. The concentration of the reactant is proportional to the rate of reaction.If you have a second order reaction, then the addition of a reactant will increase the rate of reaction by a square of the concentration of the reactant. This is because you are now dividing the rate of reaction by, for example, [HNO3]2. Remember the the previous variables m, n, or p are the experimentally determined order of reactant. So a second order reaction results in squaring the concentration. Hope that helps!
