WebEnthalpy / ˈ ɛ n θ əl p i / (), a property of a thermodynamic system, is the sum of the system's internal energy and the product of its pressure and volume. It is a state function used in many measurements in chemical, … Web1245 Words. 5 Pages. Open Document. Abstract. This lab is performed in order to determine the total energy in a reaction between zinc and hydrochloric acid. The reaction is done twice, once to measure the heat of the reaction and again to determine the work done in the system. This is because Enthalpy equals heat plus work (∆H= ∆E+W).

WebJan 30, 2024 · ΔH = ΔU + ΔPV. If temperature and pressure remain constant through the process and the work is limited to pressure-volume work, then the enthalpy change is given by the equation: ΔH = ΔU + PΔV. Also at constant pressure the heat flow ( q) for the process is equal to the change in enthalpy defined by the equation: ΔH = q. chiropractor brighton
