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. [4] impact fleet services west chester ohio

"WebEnthalpy is the total heat content of a system. The enthalpy of reaction (ΔHrxn) is the change in enthalpy due to a chemical reaction. The general formula is: Δ H r x n = H f. i. n a l − H i n i t a l = q where q is heat. If ΔH rxn> 0, the reaction is endothermic (the system pulls in heat from its surroundings) " - Chemistry formula for heat
