1.a) In the electrolysis of water, how long will it take to produce 24 L of H gas at 23 atm and 26 C using an electrolytic cell through which a current of 7.9 A flows? [15 points] 1.b) For the given reaction 2HO HO + H, Vth = 1.99 V and Vrev = 1.76 V. Calculate the enthalpy of formation and Gibbs function of formation for hydrogen peroxide at standard conditions. [15 points] You can use the below table.
