`K,Ca` and `Li` metals may be arranged in the decreasing order of their standard electrode potentials as

A

K,Ca,Li

B

Li,K,Ca

C

Li,Ca,K

D

Ca,Li,K

Text Solution

Verified by Experts

The correct Answer is:
B
`Li^(+) +e^(-) to Li, E^(@)=-2.93V`
`K^(+)+e^(-) to K, E^(@)=-2.93 V`
`Ca^(+2) +2e^(-) to Ca,E^(@)=-2.87 V`
