Question
If an endothermic reaction is non - spantaneous at freezing point of water and becomes feasible at its boiling point, then
Options
A.ᐃH is - ve, ᐃS is + ve
B.ᐃH and ᐃS both are + ve
C.ᐃH and ᐃS both are - ve
D.ᐃH is + ve, ᐃS is - ve
Solution
ᐃH +ve at low temperature and ᐃS + ve at low temperature shows that reaction is non spontaneous
At high temperature (boiling point) becomes feasible
At high temperature (boiling point) becomes feasible
