Question

For the chemical reaction , the standard reaction Gibbs energy depends on temperature  (in K) as . The major component of the reaction mixture at  is:

(1) Y if   (2) Y if   (3) X if   (4) X if

Strategy:
 The major component at equilibrium is determined by the sign of . If  (Product Y is major). If  (Reactant X is major).

Step 1: Find the threshold Temp
.

Step 2: Test conditions
- At :  is positive, so X is major.
- At :  is negative, so Y is major.
Checking Option (4): , so X is major. This is correct.
