Answer 1

so4 will more reactive

Answer 2

From the reactions, we can see that X can replace Y from its sulphate, but Y can not replace X from its sulphate.

So X is more reactive than Y.

In the first reaction, X is getting oxidised and Y is getting reduced.

In simple terms, Oxygen is getting added to X and removed from Y. So X is getting oxidised and Y is getting reduced.

Or you can say that X is going from neural to +2 oxidation state. So it is oxidised.
And Y is going from +2 oxidation state to neutral. So it is getting reduced.
