1. KClO3 decomposes according to the reaction: 2KClO3 → 2KCl + 3O2
If the rate of decomposition of potassium chlorate at a certain time is determined to be 2.4 x 10-2 mol s-1, what is the rate of formation of KCl at the same time?

2. The rate law for a reaction involving only A and B is 1st order in A and 4th order in B, respectively. If the concentration of A is increased by a factor of 4 and the concentration of B is tripled the new rate will be:

3. The reaction D ---> products is first order, and the rate constant is 2.7 x 10-4 s-1. If the initial concentration of D is 3.00 M, then what is the final concentration of D after 1.1 hr?
