i) Determine the AH° for the following reaction: CH, (g) + 4F, (g) → CF, (g) + 4HF (g) Data: Standard Enthalpies of formation in kJ/mol: A,H° CH,(g) = -74.81 A,H° CF, (g) = -925.0 A,H° HF(g) =-271.1 A,H° units (kJ/mol) i1) Sketch the thermochemistry enthalpy changes for the reaction in i) on an enthalpy landscape (Hess's diagram) plot that corresponds to the equation used to calculate AH Label the levels of the reactants and products along the enthalpy changes for the different levels. 111) Does the reaction in i) result in pressure volume work? Justify your answer.
