Question

15. In a spontaneous electrochemical cell. LHE has always
a) lower oxidation potential than that of RHE
b) higher oxidation potential than that of RHS
c) higher reduction potential than that of RHE
d) same reduction potential of that of RHE.
​

Answer 1

Answer:

the answer is higher oxidation potential than that of RHS

Answer 2

The correct answer to this question is option b) higher oxidation potential than that of RHE.

Explanation:-

• An electrochemical cell in which the reaction is spontaneous is called a voltaic cell.
• This indicates that the oxidation will occur spontaneously at the anode and the reduction naturally at the cathode.
• A species with a higher reduction potential holds a higher affinity to acquire electrons and be reduced.
• On the other hand, a species with a higher oxidation potential has a higher tendency to lose electrons and be oxidized.
