WebSep 2, 2016 · (1) Δ G = Δ H − T Δ S There is an enthalpic term related to the heat a reaction produces or requires and an entropic term that is temperature-dependent. We cannot say a lot about the entropic term a priori, but we can about the enthalpic term — which is luckily what the question is about. For that, we first need to write a reaction equation (2): WebNote the enthalpy of formation is a molar function, so you can have non-integer coefficients. For example, the molar enthalpy of formation of water is: H 2 (g) + 1/2O 2 (g) --> H 2 O (l) ΔH fo = –285.8 kJ/ H 2 (g) + 1/2O 2 …
