Question
A second order reaction requires 70 min to change the concentration of reactants from 0.08 M to 0.01 M. How much time will it require to becomes 0.04 M ?
Options
A.0 min
B.20 min
C.30 min
D.40 min
Solution
For second order, when (a - x) = 0.01 M
k2 =
k2 =
When (a - x) = 0.04 M
k2 =
Form equations (i) and (ii)

⇒ t = 10 min
k2 =
k2 =
When (a - x) = 0.04 M
k2 =
