MCQ
What is the formula for calculating the efficiency of a galvanic cell?
Chemistry
A Efficiency = (actual voltage / theoretical voltage) x 100%
B Efficiency = (E0 cathode - E0 anode) / 100
C Efficiency = nF / Delta G
D Efficiency = Delta G / RT
Explanation

Cell efficiency is the ratio of actual (measured) voltage to the theoretical (standard) voltage expressed as a percentage, accounting for internal resistance and overpotential.
