We can calculate the Entropy Change of a chemical reaction or a system by using the change in entropy formula: ΔS = (Q/T)rev. Where, Q is the heat transfer to or from the thermodynamic system. T is the absolute temperature.

WebThere are several ways to calculate entropy. One way is by using the known values of ∆H, ∆G, and the temperature of the system and plugging these values in the equation: ∆G= ∆H -T∆S. which can be manipulated into ∆S= ∆H-∆G/T. If these values are not known, then … ∆ H= enthalpy, heat, total kinetic energy (1 st law of thermodynamics). Negative: … This data was taken from: Zumdahl, Steven S., and Susan A. Zumdahl.
