Question

(aq)+ 2Na (s)→ Ca (s)+  (aq)is a spontaneous reaction.
Activity Series =

Quizplus · Accepted Answer

The activity series shows the relative reactivity of metals, and in this reaction, calcium (Ca) is displacing sodium (Na) from its compound. However, in the given activity series, Na is more reactive than Ca, indicating that the reaction is not spontaneous, but rather requires energy input to occur. Therefore, the correct answer is B.

(Aq)+ 2Na (S)→ Ca (S)+ (Aq)is a Spontaneous Reaction
