Question

The experimentally measured vapor pressure of SO2 at -25oC is 49.5 kPa and at 0oC is 155 kPa. Determine the enthalpy of vaporization, ΔHvap, at 100 oC.

A. 4150 torr

B. 3230 torr

C. 8549 torr

D. 9821 torr

Answer 1

Answer :-

Using the clausius Clapeyron equation, the enthalpy of vaporization is calculated as enthalpy of vaporization remains constants.
