NEET Chemistry Chemical Kinetics Questions Solved


For the reaction:

[Cu(NH3)4]2+ + H2O[Cu(NH3)3H2O]2+ + NH3

the net rate of reaction at any time is given by, net rate =

20x10-4 [Cu(NH3)4]2+[H2O] - 3.0x105 [Cu(NH3 )3 H20]2+[NH3]

Then correct statement is/are :

(a) rate constant for forward reaction = 2 x 10-4

(b) rate constant for backward reaction = 3 x 105

(c) equilibrium constant for the reaction = 6.6 x 10-10

(d) all of the above

(d) Net rate of reaction = rate of forward reaction - rate of backward reaction

                                   = Kf[reactants] – Kb[product]

   Also Kc =Kf/Kb at equilibrium.
