How will decreasing the reactant concentration affect the rate of reaction?
Decreasing the reactant concentration will slow the rate of the reaction. If you use the idea of adding oxygen and hydrogen to make water and decease the amount of one, you will produce less water. It doesn't matter which reactant is less as there are just are not enough to go around.
What happens to the yield of ammonia when the concentration of reactant is increased?
Increasing the concentration of reactants typically increases the yield of ammonia. According to Le Chatelier's principle, the equilibrium will shift to the right to counteract the increase in reactant concentration, favoring the production of more ammonia.
How is the effect of concentration changes on the reaction rate seen in the rate?
That depends on the order of the reaction. If the reaction is zero order with respect to a reactant, then changing the concentration will have no effect on rate. If it is first order, then doubling the concentration will double the rate. If it is second order, then doubling the concentration will quadruple the rate.
What is the silver ion concentration in a solution prepared by mixing 427 mL of 0.395 M silver nitrate with 457 mL of 0.532 M sodium chromate?
To find the concentration of silver ions in the final solution, you must first identify the limiting reactant based on the stoichiometry of the reaction. Once you determine the limiting reactant, calculate the amount of silver ions present in the solution by multiplying the initial concentration of silver ion from the limiting reactant by the volume of the limiting reactant used.
What is the definition of excess reactant?
An excess reactant is a reactant in a chemical reaction that is present in a quantity greater than required for the reaction to take place. It is not completely consumed during the reaction, leaving some of it leftover.
If you double a concentration of a reactant then the rate of the reaction doubled The order with respect to the reactant is?
The reaction is first order with respect to the reactant. In a first-order reaction, the rate is directly proportional to the concentration of the reactant. Doubling the concentration of a reactant will result in a doubling of the reaction rate.
If the order of a chemical reaction with respect to one of its reactants is zero how does that reactant's concentration affect the rate of the chemical reaction?
If the order of a reactant is zero, its concentration will not affect the rate of the reaction. This means that changes in the concentration of the reactant will not change the rate at which the reaction proceeds. The rate of the reaction will only be influenced by the factors affecting the overall rate law of the reaction.
Did a chemical reaction take place if a reactant is smaller?
Yes. If Concentration of a reactant has decreased, that means that that concentration was used in the formation of a product.
What is the effect on the rate of a chemical reaction when the concnetration of a reactant is decreased?
Decreasing the concentration of a reactant will typically decrease the rate of a chemical reaction, as there are fewer reactant molecules available to collide and form products. This is in line with the rate law, which often shows a direct relationship between reactant concentration and reaction rate.
How the limiting reactant control the product?
The yield of the reaction depends in this case only on the concentration of the limiting reactant.
How will decreasing the reactant concentration affect the rate of reaction?
Decreasing the reactant concentration will slow the rate of the reaction. If you use the idea of adding oxygen and hydrogen to make water and decease the amount of one, you will produce less water. It doesn't matter which reactant is less as there are just are not enough to go around.
Why is a catalyst not a product or reactant of a chemical reaction?
If a substance is a reactant or product of a chemical reaction then, by definition, it cannot be a catalyst.

What are 4 ways the rates of chemical reactions can vary?
Chemical reactions proceed via the formula: R=k[a]x [b]y/[ab]c Where R= reaction rate k= constant [a] = concentration of first reactant [b]= concentration of second reactant [ab]= concentration of product x,y,c = exponential that are unique to every reaction. R therefore varies by: Concentration of reactant a Concentration of reactant b Concentration of product ab Value of reaction constant k Reaction rate can also be affected by temperature but that's an entirely different equation. The Arrhenius equation.
What is the formula for half-life?
In chemistry, the half-life of a reaction is defined as the time needed for the concentration of a reactant to decrease to half of its initial concentration. According to that definition, the half-life of the reaction will be t1/2 = 0,693/k where k is the equilibrium constant for that reaction at a specific temperature.
How do you find the rate order of a concentration of a substance using a graph?
The rate order of a concentration of a substance using a graph depends on the constant k. For a reactant concentration versus time graph, k is minus and the order is zero. The same goes for a logarithm reactant concentration versus time graph where the order is one. But for an inverse of reactant concentration versus time graph, the order is two and k is positive. All these graphs should have straight lines and k is the value of the slope.
