Final answer:

A positive Gibbs free-energy value is an indication of a nonspontaneous process.

Step-by-step explanation:

A positive Gibbs free-energy value is an indication of a nonspontaneous process. The Gibbs free energy (G) is a state function that can be used to predict the spontaneity of a process. A positive value for AG indicates a nonspontaneous process, meaning that the reaction does not occur naturally or without external intervention.
