Answer #1

Q2) option c is incorrect statement since overpotential depends over electrode surface.rough surface have small overpotential required while smooth surface required large overpotential.

Q3) false statement are option 2 & 3 since polarization occur when their is difference in concentration at electrode and electryte of reactant and product.option 3 is also incorrect since overpotential also require at anodic half eg is oxidation of water which need overpotential in order to overcome activation energy.

So answer is option a.

Q5) option b is false since potential of working electrode is kept constant by varying potential of auxiliary electrode.

    b) Electrochemistry is the branch of physical chemistry that studies the relationship between electricity, as a measurable and quantitative phenomenon, and identifiable chemical change, with either electricity considered an outcome of a particular chemical change or vice versa. These reactions involve electric charges moving between electrodes and an electrolyte (or ionic species in a solution). Thus electrochemistry deals with the interaction between electrical energy and chemical change. When a chemical reaction is caused by an externally supplied current, as in...
