A reaction of the form aA---> Products is second order with a rate constant of 0.169 L/(mol*s). If the intial concentration of A is 0.159 mol/L, how many seconds would it taje for the concentration of A to decrease to 6.07X10^-3 mol/L
I think the equation for a second order reaction is
(1/A) -(1/Ao) = kt.
You know A, Ao, and k. Calculate time.
