A fuel cell designed to react grain alcohol with oxygen has the following net reaction: C2H5OH(l) + 3O2(g) → 2CO2(g) + 3H2O(l)
The maximum work that 2.00 mol of alcohol can yield by this process is 2640 kJ. What is the theoretical maximum voltage this cell can achieve? (Faraday constant = 96500 C mol⁻¹)
(A) 1.14 V
(B) 2.28 V
(C) 13.7 V
(D) 2.01 V
(E) 0.760 V
