Determine the vapor pressure of a liquid in kPa at 381 K. The enthalpy change is 31 kJ/mol. At 308 K, its vapor pressure is 25 kPa. Use this information to estimate the pressure of the vapor at the first temperature. Hint: You must put the enthalpy value into J/mol to cancel units with R.

Round your answer so that it has 1 decimal place.

R = 8.314 J/(mol*K)
