The enthalpy of vaporization (ΔHvap) for methylamine is 23.46 kJ/mol, and it has a normal boiling point of -6.4°C. Find the vapor pressure, in torr, for methylamine at -19.0°C.
Added by Catalina S.
Step 1
We can use the Clausius-Clapeyron equation to find the vapor pressure at a different temperature. The equation is: $$\ln\frac{P_2}{P_1} = -\frac{\Delta H_{vap}}{R}(\frac{1}{T_2} - \frac{1}{T_1})$$ Show more…
