We can use the sign of \Delta \text G ΔG to figure out whether a reaction is spontaneous in the forward direction, backward direction, or if the reaction is at equilibrium. When \Delta \text G<0 ΔG < 0 , the process is exergonic and will proceed spontaneously in the …

Now remember that delta G is equal to the free energy of the products of a reaction, minus the free energy of the reactants in a reaction. So if the change in Gibbs free energy is negative, which means that the products …

How can I calculate delta G of a reaction? Chemistry Q&A

https://byjus.com/question-answer/how-can-i-calculate-delta-g-of-a-reaction/

ΔG = ΔH – TΔS For a reaction to be spontaneous, the change in Gibbs free energy should be negative. Therefore, we can calculate Change in free energy ( ∆ G) by using the …
