We are asked to calculate ΔH for the change in state of 1.0 mol H2O(l) at 81 oC to H2O(g) at 115 oC.
For a constant pressure system q =ΔH
Find ΔH for the change in state of 1.0 mol H2O(l) at 81 oC to H2O(g) at 115 oC. The heat capacity of H2O(l) = 75.3 J/mol K, heat capacity of H2O(g) = 25.0 J/mol K, and the heat of vaporization of H2O is 40.7 103/mol at 100 oC.
