Answer:
Endergonic reaction or nonspontaneous reaction.
Explanation:
Gibbs free energy is a state function that determines the spontaneity or feasibility of the given reversible chemical reaction, at fixed pressure and temperature. It is given by the equation:
ΔG = ΔH - TΔS
Here, ΔG - change in Gibbs free energy
ΔH- The change in enthalpy of reaction
ΔS - The change in entropy
T- Temperature
When the <u>change in the Gibbs free energy for a given reaction is positive</u> (ΔG > 0), then that chemical reaction is known as an endergonic reaction or nonspontaneous reaction.
The answer would be letter A.Among the alkali earth metals, the tendency to react with other substances <span>increases from bottom to top within the group. We know that when there is an increase of metallic property, there will also be an increase of reactivity. </span>
