Question

Which of the following changes will always be true for a system with increasing entropy?

Answer 1

Answer:- The answer is $+\Delta S$ .

Explanations:- Negative value of delta G indicates a spontaneous reaction. From Gibb's free energy equation:

$\Delta G=\Delta H-T*\Delta S$

From this equation, delta G is more negative if delta H is negative and delta S is positive.

If the entropy is increasing then it means delta S is positive but just by looking at the delta S, we can't say if delta G is negative as delta H and temperature also plays an important role.

So, the only right option is + delta S.
