WebMar 13, 2024 · In a chemical reaction, delta H represents the sum of the heats of formation, commonly measured in kilojoules per mol (kJ/mol), of the products minus the sum of those of the reactants. The letter H in this form is equal to a thermodynamic quantity called enthalpy, representing the total heat content of a system. WebDelta h in chemistry, also written as ∆H, refers to the change of enthalpy in a thermodynamic system caused by either absorption or emission of thermal energy. In simpler words, we may elaborate delta h as the total change in the system’s heat before and after a chemical reaction. Delta is symbolically represented by ∆and refers to “change”.
