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 …
WebSep 2, 2024 · In this case, ∆T would be calculated as follows: ∆T = T2 – T1 = 95K – 185K = -90K. 5. Use the formula ∆H = m x s x ∆T to solve. Once you have m, the mass of your reactants, s, the specific heat of your product, and ∆T, the temperature change from your reaction, you are prepared to find the enthalpy of reaction.
