1.	What is the standard reduction potential of the cathode of a galvanic cell if the standard EMF of the cell and the standard reduction potential of the anode are 2.71 and -2.37 respectively?(a) 0.68 volts(b) -0.68 volts(c) -0.34 volts(d) 0.34 voltsThe question was asked by my college professor while I was bunking the class.This key question is from Electrochemistry topic in portion Electrochemistry of Chemistry – Class 12
Answer» Correct OPTION is (d) 0.34 volts Explanation: Given, STANDARD EMF of the cell = E°cell = 2.71 volts Standard REDUCTION potential of the ANODE = E°anode = -2.37 volts E°cell = E°cathode – E°anode E°cathode = E°cell + E°anode = 2.71 + (-2.37) = 0.34 volts.
