Interpretation:
This is to be explained how exothermic reaction changes the entropy of the surroundings.
Concept introduction:
The free energy change

Answer to Problem 98A
Enthalpy change
Explanation of Solution
Simple equation for the entropy change of the surrounding is
Since, exothermic reaction gives away heat to the surrounding. Therefore, changing the entropy of surrounding.
Since,
As exothermic reaction increases
