Question

derive gibbs energy equation​

Answer 1

• The Gibbs free energy is defined by G=H+TS. When we are interested in a process that converts some state A to a second state B at constant pressure and temperature, we usually write ΔG=ΔH+TΔS, relying on the context for the information about the pressure and temperature and the initial and final states.

Answer 2

Explanation:

Summary. At constant temperature and pressure, the change in Gibbs free energy is defined as Δ G = Δ H − T Δ S \Delta \text G = \Delta \text H - \text{T}\Delta \text S ΔG=ΔH−TΔSdelta, start text, G, end text, equals, delta, start text, H, end text, minus, start text, T, end text, delta, start text, S, end text.
