WebSep 8, 2024 · Not all reaction is like this but, exothermic reactions are usually spontaneous because molecules always want to be more stable. So by reacting to another molecule and releasing energy, they can lower their own energy thus making them more stable and unreactive.

Enthalpy change of the reaction can be given as the difference of bond energies of reactants and products. D. In exothermic processes, energy is released, i.e., ΔH = -ve. Thus: (A) Spontaneous process. II. ΔGT,P <0 (Constant temperature and pressure condition) (B).
WebAug 13, 2024 · Spontaneous Reactions. A spontaneous reaction is a reaction that favors the formation of products at the conditions under which the reaction is occurring.A … WebMar 20, 2016 · For a process to be spontaneous, the thermodynamic requirement is that, at constant temperature and pressure, Δ G < 0. As the entropy change of adsorption is negative ( Δ S < 0 ), the enthalpy change must therefore be negative ( Δ H < 0 ). If Δ H were to be positive, then Δ G = Δ H − T Δ S would always be positive.
WebIn chemistry, a spontaneous processes is one that occurs without the addition of external energy. A spontaneous process may take place quickly or slowly, because spontaneity is not related to kinetics or reaction rate. Now, my claim, or my intuition, based on everything we've experimented so far, is … Determining if a reaction is spontaneous by calculating the change in Gibbs free …
