NEET Solved Paper 2016 Question 19
Question: The correct thermodynamic conditions for the spontaneous reaction at all temperatures is
Options:
A) $ \Delta H<0 $ and $ \Delta S=0 $
B) $ \Delta H>0 $ and $ \Delta S<0 $
C) $ \Delta H<0 $ and $ \Delta S>0 $
D) $ \Delta H<0 $ and $ \Delta S<0 $
Show Answer
Answer:
Correct Answer: C
Solution:
- $ \Delta G=\Delta H-T.\Delta S $ For, $ \Delta H<0 $ and $ \Delta S>0,\Delta G=-ve $ (always)
$ \therefore $ spontaneous at all temperatures.
