at 25 degrees celsius the rate constant for the first order decomposition of a pesticide solution is 6.40x10^-3 min^-1. If the starting concentration of pesticide is 0.0314 M, what concentration will remain after 62.0 min @ 25 degrees celsius? Correct answer is 2.11X10^-2M Can someone please explain how to get this answer?
