For non-spontaneous process at constant T & P ΔG is
Open in App
Solution
The correct option is A Positive.
If the free energy of the reactants is greater than that of the products, the entropy of the world will increase when the reaction takes place as written, and so the reaction will tend to take place spontaneously. Conversely, if the free energy of the products exceeds that of the reactants, then the reaction will not take place in the direction written, but it will tend to proceed in the reverse direction.ΔG < 0 reaction can spontaneously proceed to the right: A → B ΔG > 0 reaction can spontaneously proceed to the left: A ← B ΔG = 0 the reaction is at equilibrium; the quantities of A and B will not change

| ΔG < 0 | reaction can spontaneously proceed to the right: A → B |
| ΔG > 0 | reaction can spontaneously proceed to the left: A ← B |
| ΔG = 0 | the reaction is at equilibrium; the quantities of A and B will not change |
