What effects does the concentration of reactions have on the rate of a reaction?
increasing the concentration increases the rate of the reaction
How is the rate of reaction affected when the temperature increases?
As the temperature increases, the reaction time decreases.
What would happen to the rate of a reaction with rate law rate kno2h3 if the concentration of no were doubled?
If the concentration of NO was doubled in the rate law rate = k[NO]2[H3], the rate of the reaction would increase by a factor of 4. This is because the rate of a reaction typically increases with an increase in the concentration of reactants, raised to a power dictated by their respective coefficients in the rate law equation.
How does an increase in temperatre affect chemical reaction?
Increases reaction rate.
You are making a new chemical but the reaction rate is really slow if you heat the reaction will most likely?
Increase the reaction rate. Heating the reaction increases the kinetic energy of the molecules, leading to more frequent and energetic collisions, which in turn increases the reaction rate.
How does the factor concentration affect reaction rate?
increasing concentration increases rate of reaction as there are more particles so there is a larger chance of collision,it increases the probability of collision of the reactants.
How do you alter the reaction rate of a chemical change?
Heat - increases it Increased stirring - increases it larger surface area - increases it catalyst - usually increases it and the reverse of the above slows the reaction down

What effect of concentration of reactants have on the rate of a reaction?

How can one determine the order of a reaction from a table?
To determine the order of a reaction from a table, you can look at how the rate of the reaction changes with the concentration of reactants. If doubling the concentration of a reactant doubles the rate, the reaction is first order with respect to that reactant. If doubling the concentration quadruples the rate, the reaction is second order. And if doubling the concentration increases the rate by a factor of eight, the reaction is third order.
What effect does the concentration of reactants have on the the rate of a reaction?
The effect of concentration of reactants on rate of reaction depends on the ORDER of the reaction. For many reactions, as the concentration of reactants increases, the rate of reaction increases. There are exceptions however, for example a zero order reaction where the rate of reaction does not change with a change in the concentration of a reactant.
Is the rate constant dependent on temperature?
Yes, the rate constant of a reaction is typically dependent on temperature. As temperature increases, the rate constant usually increases as well. This relationship is described by the Arrhenius equation, which shows how the rate constant changes with temperature.
How does concentration affect the rate of a chemical reaction?
Increasing the concentration of the reactants increases the rate of the reaction.
