Rate Laws and Order of Reactions starts at 11 and continues till grade 12. QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Rate Laws and Order of Reactions. How you perform is determined by your score and the time you take. When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.

A reaction has the rate law: rate = k. What is the effect of increasing the concentration of the reactant?
A reaction has the rate law: rate = k[A][B]. If the initial rate is 0.10 mol/L·s when [A] = 0.2 mol/L and [B] = 0.5 mol/L, what is the value of k?
A reaction has the rate law: rate = k[A][B]^2. If [A] is doubled and [B] is tripled, by what factor does the rate increase?
A reaction has the rate law: rate = k[A]^0.5. What is the order of the reaction with respect to A?
A reaction has the rate law: rate = k[A]^2. If the rate constant k is 0.5 L/mol·s and [A] = 0.4 mol/L, what is the rate?
A reaction is first order in A and zero order in B. If [A] is doubled and [B] is tripled, by what factor does the rate increase?
A reaction is second order overall. If the concentration of the reactant is doubled, by what factor does the rate increase?
Explain why the rate law for a reaction cannot generally be predicted from the stoichiometric equation alone.
For a reaction with rate law rate = k[A]^2, what happens to the rate if [A] is reduced to one-third of its original value?
Given the following data for the reaction A → products: [A] (mol/L): 0.10, 0.20, 0.40; Initial rate (mol/L·s): 0.02, 0.08, 0.32. What is the order of the reaction with respect to A?
Given the rate law: rate = k[A]^2[B], what is the order of the reaction with respect to B?
If doubling the concentration of reactant A doubles the rate of the reaction, what is the order of the reaction with respect to A?
The rate law for a reaction is rate = k[A][B]. If the concentration of A is halved and B is doubled, what happens to the rate?
The rate law for a reaction is rate = k[A]^0[B]^1. What is the order of the reaction with respect to A?
The rate law for a reaction is rate = k[A]^2[B]. What is the overall order of the reaction?
