STANDARD Chemistry Standard Electrode Potentials MCQ Question

Type: MCQ-conceptual-Medium-Class 12

The standard reduction potential for the half-cell reaction, Cl₂ + 2e⁻ → 2Cl⁻ will be (Pt²⁺ + 2Cl⁻ → Pt + Cl₂, E° cell = -0.15 V; Pt²⁺ + 2e⁻ → Pt, E° = 1.20 V)

A

-1.35 V

B

+1.35 V

C

-1.05 V

D

+1.05 V

Correct Answer

Option B

Detailed Explanation

The standard reduction potential is calculated using the given cell potentials. E° cell = E° cathode - E° anode. Here, E° cell = 1.35 V.
