(C) The relationship between the equilibrium constant $(K_c)$,the forward rate constant $(K_f)$,and the backward rate constant $(K_b)$ is given by: $K_c = \frac{K_f}{K_b}$ Given: $K_b = 7.5 \times 10^{-4}$ $K_c = 1.5$ Therefore,the forward rate constant is: $K_f = K_c \times K_b$ $K_f = 1.5 \times 7.5 \times 10^{-4}$ $K_f = 1.125 \times 10^{-3}$
