Answer:
- A chemical reaction that has a positive δG is best described as non-spontaneous.
Step-by-step 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:
- δG < 0 spontaneous reaction
- δG = 0 equilibrium
- δG > 0 non spontaneous reaction
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.
