WebDec 17, 2024 · And the major equation that describes this is: ∆G = ∆H – T∆S. In English, that says “the change in free energy (G) equals the change in enthalpy (H) minus temperature (T) times the ... WebAt high temperatures, the value of T∆S becomes increasingly large and may dominate the value of ∆H, causing ∆G to be negative and making the reaction spontaneous. Therefore, the dissociation of ammonium nitrate is spontaneous at high temperatures, but at low temperatures, ∆G may become positive and the reaction would not occur ...
