Chemical Thermodynamics Question 406
Question: In an irreversible process taking place at constant T and P and in which only pressure-volume work is being done, the change in Gibbs free energy (dG) and change in entropy (dS), satisfy the criteria
Options:
A) $ {{(\Delta S)} _{V,E}}>0,{{(\Delta G)} _{T,P}}<0 $
B) $ {{(\Delta S)} _{V,E}}=0,{{(\Delta G)} _{T,P}}=0 $
C) $ {{(\Delta S)} _{V,E}}=0,{{(\Delta G)} _{T,P}}>0 $
D) $ {{(\Delta S)} _{V,E}}<0,{{(\Delta G)} _{T,P}}<0 $
Show Answer
Answer:
Correct Answer: A
Solution:
- For spontaneous reaction, $ dS>0 $ and $ \Delta G $ and $ \Delta G $ should be negative i.e. < 0.
