For the reaction

`k_(1) = 1.78 xx 10^(-3)s^(-1)` and `k_(2) = 5.8 xx 10^(-5)s^(-1)` for the initial concentration of `[Cr(H_(2)O)_(4)Cl_(2)]^(o+)` is `0.0174 mol L^(-)` at `0^(@)C`. Calculate the value of time at which the concentration of `[Cr(H_(2)O)_(5)Cl]^(2+)` is maximum.

Text Solution

Verified by Experts

We have ,
`t = (2.303 (logk_(1) - log k_(2)))/(k_(1)-k_(2)) " " ...`
`= (2.303 (log 1.78 xx10^(-3) - log 5.8 xx10^(-5)))/(1.78 xx10^(-3) - 5.8 xx10^(-5))`
= 1990 seconds .
