MCQ
The sign of $\Delta\text{G}$ for a spontaneous and non $-$ spontaneous process respectively are :
- APositive and negative.
- ✓Negative and positive.
- CZero and positive.
- DPositive and zero.
✓
Answer
Correct option: B.
Negative and positive.
gives a criteria for spontaneity at constant pressure and temperature.
- If $\Delta\text{G}$ is negative $(< 0),$ the process is spontaneous.
- If $\Delta\text{G}$ is positive $(> 0),$ the process is non$-$spontaneous.
