WebDec 1, 2024 · Catalyst remains chemically unchanged at the end of a reaction. It means that the quantity and chemical composition of the catalyst remain unchanged at the end of the reaction. Catalyst alters the rate of a chemical reaction. Positive catalyst increases the rate of reaction. Negative catalyst decreases the rate of reaction. WebThe magnitude of ΔH is dependent upon the amounts of reactants consumed. Doubling the reactants, doubles the amount of enthalpy. 2.Reversing a chemical reaction results in the same magnitude of enthalpy but of the opposite sign. 3.The enthalpy change for a reaction depends upon the state of the reactants and products.
