Electrochemistry: NEET questions with solutions

NEET tests E°cell and ΔG° = −nFE°, the Nernst equation, Faraday's laws, conductivity versus molar conductivity on dilution, Kohlrausch's law with degree of dissociation, electrolysis products and batteries. Marks are lost on the value of n, on the sign inside the Nernst log term, on the 1000 factor in Λm, and on which product forms when water competes at an electrode.
