JEE Main2002ChemistryThermodynamics (C)Actual
If an endothermic reaction is non- spantaneous at freezing point of water and becomes feasible at its boiling point, then
Options
- AH is - ve, S is + ve
- BH and S both are + ve
- CH and S both are - ve
- DH is + ve, S is - ve
Correct answer
B. H and S both are + ve
Step-by-step solution
H +ve at low temperature and S +ve at low temperature shows that reaction is non spontaneous At high temperature (boiling point) becomes feasible
