The table below summarises how three metals, P, Q and R, behave. P: with dilute hydrochloric acid: yes; with water: no. Q: with dilute hydrochloric acid: no; with water: no. R: with dilute hydrochloric acid: yes; with water: yes. What is the reactivity order of these metals?
- Amost reactive P → Q → R least reactive
- Bmost reactive Q → R → P least reactive
- Cmost reactive R → Q → P least reactive
- Dmost reactive R → P → Q least reactive
