A, B and C are three elements which undergo chemical reactions according to following equations.
`A_(2)O_(3) + 2B to B_(2)O_(3) + 2A`
`3CSO_(4) + 2B to B_(2)(SO_(4))_(3) + 3C`
`3CO + 2A to A_(2)O_(3) + 3C`
Answer the following questions :
(a) Which element is the most reactive ? (b) Which element is the least reactive ?

Text Solution

Verified by Experts

(a) The most reactive element is 'B' as it has displaced both 'A' and 'C' from their compounds.
(b) The least reactive element is 'C' as it has been replaced by both 'A' and 'B'.
