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[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. If [A] is increased from 0.25 M to 1.00 M, by what factor does the rate increase?
A reaction has the rate law rate = k[A]2. If the rate is 0.16 M/s when [A]=0.4 M, what is the rate when [A]=0.2 M?
A reaction has the rate law rate = k[A]2[B]. What is the effect on the rate if [A] is doubled and [B] is kept constant?
A reaction is zero order in reactant A. What happens to the rate if the concentration of A is doubled?
For a reaction with rate law rate = k[A][B], what is the overall order of the reaction?
For a reaction with rate law rate = k[A]2, if the initial rate is 0.10 M/s when [A]=0.5 M, what is the value of k?
For a reaction with rate law rate = k[A]2[B], what is the effect on the rate if [A] is halved and [B] is doubled?
For the reaction 2A + B → C, the experimentally determined rate law is rate = k[A][B]. What is the order with respect to A and the overall order?
If doubling the concentration of reactant A doubles the rate of the reaction, what is the order of the reaction with respect to A?
If the rate law for a reaction is rate = k[A]1[B]1, what is the effect on the rate if both [A] and [B] are doubled?
If the rate law for a reaction is rate = k[A]1[B]2, and the rate increases by a factor of 8 when [B] is doubled, what is the order with respect to B?
If the rate law for a reaction is rate = k[A]1[B]2, what is the effect on the rate if [A] is doubled and [B] is tripled?
The rate law for a reaction is rate = k[A][B]. If the concentration of A is tripled and B is doubled, by what factor does the rate increase?
The rate law for a reaction is rate = k[A][B]. If the rate constant k = 0.2 L mol-1 s-1, [A]=0.1 mol/L, and [B]=0.2 mol/L, what is the rate?
The rate law for a reaction is rate = k[A]0.5. What is the order of the reaction?
The rate law for a reaction is rate = k[A]0[B]1. What is the overall order of the reaction?
The rate law for a reaction is rate = k[A]1[B]0. If [A] is doubled, what happens to the rate?
