If a reaction has a ΔG°' of +10 kJ/mol, which of the following conditions could make the reaction proceed spontaneously?

Question

A) Increase the temperature to increase the entropy of the products.

B) Increase the concentration of the products.

C) Decrease the concentration of the reactants.

D) Both A and C.

Answer 1

Gibbs free energy equation is: ΔG=ΔH−TΔS\ΔG

 shows Increase the temperature to increase the entropy of the products

And with the equationΔG=ΔG°′+RTln⁡(Q)\ ΔG = \ ΔG°' + RT \ln(Q)ΔG=ΔG°′+RTln(Q)

Decreasing the concentration of reactants decreases Q, which can also affect ΔG.

Answer is D) A and C
