1. The problem statement, all variables and given/known data

In a first order decomposition, the constant is 0.00313 sec-1. What percentage of the compound has decomposed after 7.17 minutes?

2. Relevant equations

rate = ln[A]_{o}- ln[A]_{t}= kt

3. The attempt at a solution

I feel bad because I have no idea how to solve this problem. My 1st test is soon to come, please help me!
