Question

Cost of electricity for the production of ′X′ litre H2 at NTP at cathode is Rs. X, then cost of electricity for the production ′X′ litre O2 gas at NTP at anode will (assume 1 mole of electrons as one unit of electricity)

Options

A.2X
B.4X
C.16X
D.32X

Solution

For same charge passed mole of H2 produced = 2 × moles of O2 produced.
