Consider the process

which is carried out at constant pressure. The total DS for this process is known to be 75.0 J K-1mol-1. For A(l) and A(g), the Cp values are 75.0 JK-1mol-1 and 29.0 JK-1mol-1, respectively, and are not dependent on temperature. Calculate Î”H vaporization for A(l) at 125oC (its boiling point).
