(c) Remains same

(d) First increases then decreases

The question was asked by my college director while I was bunking the class.

My doubt is from Galvanic Series topic in chapter Corrosion, Electrolysis, Fuel Cells and Batteries of Engineering Chemistry II

Answer 1

The correct option is (a) Increases
