Gasoline is a mixture of hydrocarbons, but the heat released when it burns is close to that of octane, C₈H₁₈(l) ( ΔHf° = -250.1 kJ/mol). Research is underway to use H₂ from the electrolysis of water in fuel cells to power cars instead of gasoline.(c) How long would it take to produce this amount of H₂ by electrolysis with a current of 1.00X10³ A at 6.00 V?
