Which statement about standard reduction potentials is correct?

A

`E_(H^-//H_2)^@` gt 0

B

`E_(D^1//D_2)^@` lt 0

C

A redox reaction is feasible if sum of SRP of oxidant and that of reductant is a positive quantity

D

`K_2Cr_2O_7` is stronger oxidising agent than `KMnO_4` in acidic medium

Text Solution

Verified by Experts

The correct Answer is:
C

For a spontaneous reaction, `DeltaD=-Ve`
which is possible if `"^@E` is +ve because, `DeltaG=-nFE^@`

Standard reduction potentials (SRP) for different systems can be used to decide the spontaneity of a reaction e.g., E_(2n^(2+)//Zn)^(@)=-0.76V , hence for the reaction Zn+2H^(+)rarrZn^(2+)+H_(2),DeltaG^(@) is negative. It has been found experimentally that if (SRP of an oxidant-SRP of a reductant) is more than 1.7V, then their combination may lead to explosion (though it may be prevented by kinetic factors).
