Chemistry · May / June 2024 · Paper 11 · Question 30

The table shows the reactions of four metals, P, Q, R and S, and their oxides. | | reaction with water | reaction with dilute acid | reaction of oxide with carbon | |---|---|---|---| | P | reacts only with steam | reacts rapidly | no reaction | | Q | no reaction | reacts slowly | reacts when heated strongly | | R | no reaction | no reaction | reacts when heated | | S | reacts rapidly | reacts rapidly | no reaction | What is the order of reactivity, from the most reactive to the least reactive metal?

1. AP > S > Q > R
2. BP > S > R > Q
3. CS > P > Q > R
4. DS > P > R > Q
