The correct option is d) The standard cell potential for the redox couple
Explanation:
- To understand the factors we need to know what is polarization.
- It is the barrier that is developed at the interface of the electrode and the electrolyte due to some mechanical side-effect.
- Some of the factors which affect the polarization at an electrode include the viscosity of the electrolyte, material's insolating layer, charge or discharge rate etc.
- But The standard cell potential for the redox couple is not a factor that affects the polarization at an electrode.
