Question

For the reaction \( A(g) + \frac{1}{2} B(g) \rightleftharpoons C(g) + \text{heat} \), the favorable conditions for the forward reaction are:

• A. Low \( T \) and low \( P \)
• B. Low \( T \) and high \( P \)
• C. High \( T \) and low \( P \)
• D. High \( T \) and high \( P \)

Hint:

Exothermic + decrease in moles: Low T and High P favor the forward direction.

Answer 1

The Correct Option is B

According to Le Chatelier’s principle: - The reaction is exothermic, so low temperature favors forward direction.
- Gaseous moles decrease: from \( 1 + 0.5 = 1.5 \to 1 \), so high pressure favors forward direction.
Thus, favorable conditions: Low Temperature and High Pressure
