For the reaction:
[Cu(NH3)4]2++H2O  ⇋  [Cu(NH3)3H2O]2++NH3,{\left[ {\mathrm{Cu}{{\left( {\mathrm{N}{\mathrm{H}_3}} \right)}_4}} \right]^{2 + }} + {\mathrm{H}_2}\mathrm{O}\;\leftrightharpoons\;{\left[ {\mathrm{Cu}{{\left( {\mathrm{N}{\mathrm{H}_3}} \right)}_3}{\mathrm{H}_2}\mathrm{O}} \right]^{2 + }} + \mathrm{N}{\mathrm{H}_3}, the net rate of reaction at any time is given by, net rate=2.0×10−4  [Cu(NH3)4]2+[H2O]−3.0×105[Cu(NH3)3H2O]2+⋅[NH3]rate = 2.0 \times {10^{ - 4}}\;{\left[ {\mathrm{Cu}{{\left( {\mathrm{N}{\mathrm{H}_3}} \right)}_4}} \right]^{2 + }}\left[ {{\mathrm{H}_2}\mathrm{O}} \right] - 3.0 \times {10^5}{\left[ {\mathrm{Cu}{{\left( {\mathrm{N}{\mathrm{H}_3}} \right)}_3}{\mathrm{H}_2}\mathrm{O}} \right]^{2 + }} \cdot \left[ {\mathrm{N}{\mathrm{H}_3}} \right]
Then correct statement is/are:
View answer and explanation
Correct option: D
All of the above
Option A (1.5K1=3K2=K31.5{K_1} = 3{K_2} = {K_3}) is correct because it correctly relates the rate constants based on the stoichiometry of the given reaction.
