Given that the order of reactivity of four metals is P>Q>R>S, which of the following reactions is feasible?

Assessment: WAEC SSCE - Chemistry - 2001 (Objective) Subject: Chemistry

Question 1 Report

Given that the order of reactivity of four metals is P>Q>R>S, which of the following reactions is feasible?
Answer Details
Feasible reactions between two metals occur when the metal higher in the reactivity series displaces the metal lower in the reactivity series from its compound. Based on the given order of reactivity (P>Q>R>S), feasible reactions will occur between P and Q, R and S, and P and S. Therefore, the only feasible reaction from the options provided is: Q + S+ → S + Q+
