WebThe Van 't Hoff equation relates the change in the equilibrium constant, K eq, of a chemical reaction to the change in temperature, T, given the standard enthalpy change, Δ r H ⊖, for the process.It was proposed by Dutch chemist Jacobus Henricus van 't Hoff in 1884 in his book Études de Dynamique chimique (Studies in Dynamic Chemistry). This equation is … WebThe temperature is that of both the system and surroundings. The whole point of "free energies" is that you must imagine: The system to be in thermodynamic equilibrium at all times so that, a fortiori this means that the system and environment must be at the same temperature, and, The system's thermodynamic macrostate to be "cycled", i.e., …
