According to the given conditions, the reactivity of the metals is in the order:
R>Q>P
R is more reactive than Q , which is more reactive than P.
The reactivity order of these metals can be determined experimentally by any of the following methods:
1. Metal displacement reactions- involving reaction between metal and salt solution.
2. Metal reaction with Hydrochloric acid( HCl).
3. Metal reactivity with water.
4. Heating the respective metal carbonates.
