For this problem, we can use the Clausius-Clapeyron Equation:
P1 = vapor pressure at T1
P2 = vapor pressure at T2
ΔHvap = heat of vaporization (in J/mol)
R = gas constant (8.314 J/mol•K)
T1 and T2 = temperature (in K).
What is the vapor pressure of mercury at 25°C if its enthalpy of vaporization is 59.1 kJ/mol? Note that the normal boiling point of mercury is 357°C.
