WebThe entropy would decrease If the process were an isothermal compression. Isochoric process An isochoric process is a process which takes place at constant volume (V = constant). The entropy change between states A and B is given by: Where C V is the molar heat capacity at constant volume. WebApr 6, 2013 · There comes my question, we find out that this isochoric process is irreversible but when we use the equation dS = dQ/T, we could only use it in reversible process. I try to solve this problem by constructing 1 isotherm and 1 adiabat to replace original isochoric path and find out that dS actually = dQ / T = Cv/T dT ,
