Web2 sep. 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. http://scientifictutor.org/1663/chem-how-to-calculate-delta-h/
