Problem- The vapor pressure of benzene is 331 mmHg at 60.6EC. What is the vapor pressure at 15.0EC? The molar heat of vaporization of benzene is 31.0 kJ/mol.
Please explain step by step. I am using the formula
ln(p2/p1)= -DeltaHvap/R (1/t2- 1/t1) and getting 330mmHg, the answer is 56.5
I need proficient help to solve the above problem
