Will the transformation of ice into water be spontaneous at `-2^(@)C` and 1 atm pressure? Will the reverse process be spontaneous at this pressure and temperature?

Text Solution

Verified by Experts

No. The transformation of ice into water at `-2^(@)C` and 1 atm pressure is not spontaneous. This is because the sum of the increase in entropy of the system and the decrease in entropy of the surrounding is less than zero. The reverse process, i.e., the transformation of water into ice is spontaneous. this is because at `-2^(@)C` and 1 atm pressure the sum of the decrease in entropy of the system and the increase in entropy of the surroundings is greater than zero.
