WebSep 16, 2024 · For a chemical reaction, the enthalpy of reaction ( ΔHrxn) is the difference in enthalpy between products and reactants; the units of ΔHrxn are kilojoules per mole. Reversing a chemical reaction reverses the sign of ΔHrxn. Contributors and Attributions Modified by Joshua Halpern ( Howard University) 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.
