Question

on the basis of the sequence of reactions identify the most and least elements - A+BX---->AX+B C+AY---->CY+A

Answer 1

1) A+BX---->AX+B

From this: A>B (More reactive)

Becauses it displaces B from it's solution.

2) C+AY---->CY+A

From this: C>A

Therefore:

B<A<C (Increasing reactivity order.)
