Achemical reaction that has a positive δg is best described as

Explanation:

G is the symbol used for the Gibss energy, also known as free energy.

G measures the useful energy, i.e. the energy that can be used to perform a work.

G = H - TS and the change in G is given by δG = δH - TδS.

The sign of δG tells if a chemical reaction is spontaneous or not.

If δG is positive the reaction is non-spontaneous, if δG is negative the reaction is spontaneous, and if δG = 0 the reaction is at equilibrium. This can be written as:

Then, as to the given statement, it is completed with the term non-spontaneous, which corresponds to the description of a chemical reaction that has a positive δG.
