Question

For the process $\frac{3}{2}A \rightarrow B$, at 298 K, $\Delta G^\circ$ is $163\ \text{kJ mol}^{-1}$. The composition of the reaction mixture is $[B]=1$ and $[A]=10000$. Predict the direction of the reaction and the relation between reaction quotient $(Q)$ and the equilibrium constant $(K)$.}

• A. forward direction because $Q > K$
• B. reverse direction because $Q > K$
• C. forward direction because $Q < K$
• D. reverse direction because $Q < K$
• E. it is at equilibrium as $Q = K$

Hint:

Always compare $Q$ with $K$:
• $Q < K$ → forward reaction
• $Q > K$ → backward reaction
• Large $+\Delta G^\circ$ → very small $K$

Answer 1

The Correct Option is B
