Question

what is enthalpy and entropy?

Open in App
Solution

Enthalpy may be defined as the energy supplied to the system or gain from the system at constant pressure. Mathematically it is called the sum of internal energy and pressure-volume work.

H = U + PV

Entropy may be defined as the measurement of disorderness or randomness in a system. It is denoted by S. For any reversible reaction the change in entropy may be defined as ratio of energy Q and Temperature T.

ΔS = Q/ΔT.
