1. A certain rate law is given as Rate = k[H2][Br2]1/2. What is the reaction order?

a. ½ b.3/2c. ¾ d. 1/3

2. Using the integrated form of the rate law, determine the rate constant k of a zero-order reaction if the initial concentration of substance A is 1.5 M and after 120 seconds the concentration of substance A is 0.75 M. 

a. 0.00625 M/s b. 0.00875 M/s c. 0.00986 M/s d. 0.0096 M/s

3. Determine the half-life of zero-order reaction if the original concentration of the reactant is 1.2 M and the rate constant ko = 0.00625 M/s?

a. 625 s b. 69 s c. 96 s d. 62500 s
