Question

Considering a reaction with AH = -75 kJ/mol and A9 = -0.081 kJ/(K*mol), at what temperature does this reaction become spontaneous?

A. Above 925 K
B. Below 925 K
C. At 925 K
D. Not determinable from the given information

Answer 1

The reaction is never spontaneous based on the signs of AH and AS.

Step-by-step explanation:

The reaction AH = -75 kJ/mol and A9 = -0.081 kJ/(K*mol) is not spontaneous at any temperature.

The signs of AH and AS indicate whether a reaction is spontaneous or nonspontaneous. In this case, AH is negative but AS is positive, which means the reaction is never spontaneous.

Therefore, the correct answer is D. Not determinable from the given information.
