Question

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 energy

Answer 1

Answer:

A. Gibbs free energy is positive

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.
