AIIMS 2019 Chemistry Equilibrium Constants MCQ Question

In the context of chemical equilibrium, the equilibrium constant $K_e$ for the forward reaction $A + B \rightleftharpoons C$ is given by $K_e = \frac{[C]}{[A][B]}$. For the reverse reaction $C \rightleftharpoons A + B$, the equilibrium constant is $K_e' = \frac{[A][B]}{[C]}$. Since the reverse reaction is simply the inverse of the forward reaction, it follows that $K_e' = \frac{1}{K_e}$, confirming that $K_e \cdot K_e' = 1$. The other options are not relevant as they do not provide any additional information or correct interpretations of the equilibrium constants.
