WebJan 11, 2024 · Delta H reaction = Hproducts - Hreactants This equation essentially states that the standard enthalpy change of formation is equal to the sum of the standard enthalpies of formation of the... WebJan 2, 2024 · How do you find the H RXN? 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. Simply plug your values into the formula ∆H = m x s x ∆T and multiply to solve.
