For the reaction:`[Cu(NH_3)_4]^(2+)+H_2Orarr[Cu(NH_3)_3H_2O^(2++)NH_3`the net rate of reaction at any time is given by :net rate =`2.0xx10^(-4)[[Cu(NH_3)_4]^(2+)-3.0xx10^5[[Cu(nh_3)_3H_2O]^(2+)]`.`[NH_3]`Then correct statement is (are):

Options

A. Rate constant for forward reaction`=2xx10^4`
B. Rate constant for backward reaction` =3xx10^5`
C. Equilibrium constant for the reaction` =6.6xx10^10`
D. All

Answer

B
