Question

E° for $\large F{e^{2 + }}\, + \,2e\, \to \,Fe$ is –0.44 V
E° for $\large Z{n^{2 + }}\, + \,2e\, \to \,Zn$ is –0.76 V. Then

Moderate

A

Zn is more electropositive than Fe
B

Fe is more electropositive than Zn
C

Zn is more electronegative
D

None of the above

Solution

Metal which looses electrons readily is more electropositive. Metal electrode with lesser SRP looses electrons readily and is more electropositive.
SRP of Zn electrode < SRP of Fe electrode. Hence Zn is more electropositive.
