Question

If \( K < 1.0 \), what will be the value of \( \Delta G^{\circ} \) of the following?

• A. Zero
• B. 1.0
• C. Positive
• D. Negative

Hint:

$K<1 \rightarrow \Delta G^{\circ}>0$ (Non-spontaneous); $K>1 \rightarrow \Delta G^{\circ}<0$ (Spontaneous).

Answer 1

The Correct Option is C

Step 1: Concept
The relationship is $\Delta G^{\circ} = -RT \ln K$.
Step 2: Analysis
If $K<1$, then $\ln K$ is negative.
Step 3: Conclusion
A negative value multiplied by $-RT$ results in a positive $\Delta G^{\circ}$.
Final Answer: (C)
