Enthalpy Of Different Processes

Science > Chemistry > Chemical Thermodynamics and Energetics > Heat of Reaction Of Different Processes In this article, we shall study change in enthalpy for different chemical processes. Enthalpy of Formation (ΔfH° or ΔformationH°): The change in enthalpy of a chemical reaction at a given temperature and pressure, when one mole of the substance is formed […]
