WebA student is asked to calculate the amount of heat involved in changing 10.0 g of liquid bromine at room temperature (22.5C) to vapor at 59.0C.To do this, one must use Tables 8.1 and 8.2 for information on the specific heat, boiling point, and heat of … WebApr 1, 2024 · Equation 23.4.1 is known as the Clausius-Clapeyron equation. We can further work our the integration and find the how the equilibrium vapor pressure changes with temperature: ln(P2 P1) = − ΔHvap molar R [ 1 T2 − 1 T1] Thus if we know the molar enthalpy of vaporization we can predict the vapor lines in the diagram.
