Enthalpy and Enthalpy change
The Heat content of system at constant pressure is termed as enthalpy denoted by 'H'.
From the first law of thermodynamics, Δq=E+PV ..........(i)
Heat change at the constant pressure can be given as follows
..........(ii)
At the constant pressure heat can be replaced at the enthalpy.
.........(iii)
ΔH = Heat change or heat of reaction (in the chemical process) at constant pressure
ΔE = Heat change or the heat of reaction at constant volume.
In the case of solids and liquids participating in a reaction,
Difference between the H and E is important when the gases are taking part in chemical reaction.
