Question

In a chemical equilibrium, the rate constant for the
backward reaction is 7.5 x10-4 and the equilibrium
constant is 1.5. The rate constant for the forward
reaction is:-
(1) 2 x10-3
(2) 5 x10-4
(3) 1.12 x10-3
(4) 9.0 x10-4

Answer 1

Answer:

1.125 X 10(raise to the power -3)

Explanation:

Equilibrium constant (k) is given by

K=Kf/Kb

Kf=K × Kb=1.5×7.5×10−4=1.125×10(raise to the power-3)
