How to solve for delta h vap
WebIf the enthalpy of vaporization delta H and entropy of vaporization delta S are known (for very many substances they are available in tables), set the Gibbs free energy of vaporization delta G = delta H minus T delta S = 0. Then the temperature of the boiling point is T = delta H/delta S. Why does trouton’s rule work? WebUse the hints to solve. Step 1. Step 2. Solve for the heat required to increase the water into steam (no change in temperature). Q = m x ΔHvap. Q = 52.0 g x 2260 J/g. Q = 117520 J. Step 3. Solve for the heat required to change the temperature of the steam from 100.0°C to 110.0°C.
