WebJul 28, 2024 · How do I calculate delta H from the enthalpy change formula? From the enthalpy formula, and assuming a constant pressure, we can state the enthalpy change formula: ΔH = ΔU + pΔV = (U2 - U1) + p (V2 - V1) where: ΔH — Enthalpy change; ΔU — Internal energy change; U1 — Internal energy of the reactant; U2 — Internal energy of … WebMay 21, 2024 · Step 1: Set Up the Equation. Arrange your given ΔHf and ΔH values according to the following equation: ΔH = ΔHf (products) - ΔHf (reactants). For example, imagine that you want to know ΔHf for acetylene, C 2 H 2, for the reaction C 2 H 2 (g) + (5/2)O 2 (g) --> 2CO 2 (g) + H 2 O (g), the combustion of acetylene, the ΔH of which is … fiscal katherine fernandez
