Solution: The molar heat capacity of some molecule X(l) is 10 cal/K · mol, its heat of vaporization is 5000 cal/mol and its boiling point is 75◦C. For the conversion of one mol of X(g) at 75◦C to one mol of X(l

Problem

The molar heat capacity of some molecule X(l) is 10 cal/K · mol, its heat of vaporization is 5000 cal/mol and its boiling point is 75C. For the conversion of one mol of X(g) at 75C to one mol of X(l) at 60C,

1. 5150 cal of heat are released by X. 

2. 4850 cal of heat are released by X.

3. 150 cal of heat are released by X.

4. 4850 cal of heat are absorbed by X.

5. 5150 cal of heat are absorbed by X.
