Chapter 13, Problem 13.74PAE

An electrolysis cell for aluminum production operates at 5.0 V and a current of $1.0\times {10}^5$ A. Calculate the number of kilowatt-hours of energy required to produce 1 metric ton ( $1.0\times {10}^3$ kg) of aluminum. ( $1\text{kWh}=3.6\times {10}^6$ J and $1\text{J}=1$ C V.)
