Question

If the free energy change of a reaction greater than zero, then the reaction is

• A. Spontaneous
• B. Non-spontaneous
• C. At equilibrium
• D. Endothermic

Answer 1

Answer: (B)

Non-spontaneous

The free energy change of the reaction is expressed by $\Delta G$. When the free energy change is equal to zero, the reaction is at equilibrium. When the free energy change is less than zero which means negative, the reaction is spontaneous. When the free energy change is more than zero which means positive, the reaction is non-spontaneous.

Thus, the correct answer is option B.
