The rate constant for this second-order reaction is 0.900 M–1·s–1 at 300 °C. A -> products?

How long (in seconds) would it take for the concentration of A to decrease from 0.950 M to 0.290 M?

Integrated rate equation for second-order reaction:
1/[A] = kt + 1/[A]ₒ
kt = 1/[A] - 1/[A]ₒ
Then, t = (1/[A] - 1/[A]ₒ) / k
Time taken, t = (1/0.290 - 1/0.950) / 0.900 s = 2.66 s
1/[A] = kt + 1/[A]ₒ
kt = 1/[A] - 1/[A]ₒ
Then, t = (1/[A] - 1/[A]ₒ) / k
Time taken, t = (1/0.290 - 1/0.950) / 0.900 s = 2.66 s
