Question

Energy change is governed by Heat Work Enthalpy None of these​

Answer 1

Enthalpy (H) is a measure of the energy in a system, and the change in enthalpy is denoted by ΔH . Since enthalpy is a state function, the value of ΔH is independent of the path taken by the reactions to reach the products.

Answer 2

From the given question the correct answer is :

Energy change is governed by  Enthalpy .

The change in the enthalpy of the system during a chemical reaction is equal to the change in its internal energy plus the change in the product of the pressure times the volume of the system. H = E + (PV) Let's assume that the reaction is run in a styrofoam cup
