(aq)is a spontaneous reaction.

Quizplus · Accepted Answer

The reaction involves an alkali metal (Na) being oxidized to form a cation and reducing the cation from a alkaline earth metal (Ca) to its elemental form. This reaction contradicts the activity series, as Na is more reactive than Ca and should not be able to reduce it. Therefore, the reaction is not spontaneous.
