WebNov 26, 2024 · It is shown above that the free energy of mixing is: ΔGmix = ΔHmix - TΔSmix = xAxBW + RT ( xA ln xA + xB ln xB) The shape of the ΔGmix curve is dependent on temperature . For the curve shown below the value of ΔHmix is positive, leading to a maximum on the curve at low temperatures. ΔGmix is always negative for low solute … WebWell, first we learned that enzymes work by lowering the free energy of activation of a reaction, making it much easier for the reactants to transition and form products. And we also learned that the free energy of the reaction doesn't really change when you use an enzyme and when you don't.
