Answer “The reaction rate constant is determined to be 0.012 M-1 s-1. Ifafter 27 minutes the amount of A left is 0.048 M. What was the initial concentration of A? 0.049 2.53e16 0.72 19.49”.
We have:
K = 0,012 M-1s-1 <- second order
1/A = 1/A0 + kt
1/0,048M = 1/A0 + (0,012 M-1s-1)(27min x 60s/min)
=> A0 = 0,72M
