WebJul 12, 2024 · The isentropic compressor work for an ideal gas is given by: γR(ΔT)/γ -1 . This eq is usually reduced to Cp(ΔT) ; since Cp= γR/γ - 1. So, even though there is pressure rise in compressor, we are calculating work by using specific heat at constant pressure, which is fine if we only look at this as a slight mathematical manipulation.But … WebA pop-up calculator is available to calculate the enthalpy and Gibbs free energy changes in reactions. Given a constant temperature and pressure, the direction of any spontaneous change is toward a lower Gibbs free energy. The graphic below shows that during a reaction, the amount of free energy decreases until the reaction is at equilibrium.
