When is a reaction nonspontaneous?(a) Gibbs free energy is positive(b)

1.	When is a reaction nonspontaneous?(a) Gibbs free energy is positive(b) Gibbs free energy is negative(c) Gibbs free energy is zero(d) Does not depend on Gibbs free energyI got this question in a national level competition.Question is taken from Relationship between Equilibrium Constant K, Reaction Quotient Q and Gibbs Energy G in chapter Equilibrium of Chemistry – Class 11
Answer» The CORRECT answer is (a) Gibbs FREE energy is POSITIVE Explanation: When Gibbs free energy is positive, the reaction that occurs is nonspontaneous and a reaction occurs BACKWARD that is the products are converted into reactants. SIMPLY the reverse reaction could occur.
