3 WAYS TO CALCULATE THE ENTHALPY OF A CHEMICAL REACTION
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. Simply plug your values into the formula ∆H = m x s x ∆T and multiply to solve.

ENTHALPY CALCULATOR
Enthalpy measures the total energy of a thermodynamic system — either in the form of heat or volume multiplied by pressure. It is a state function, depending only on the equilibrium state of a system. The more interesting quantity is the change of enthalpy — the total energy that was exchanged within a system. It is a simplified description of the energy transfer …
