In the electrolysis of an acid solution, oxygen can be produced by the following half-reaction: 2H20() O2(g) + 4H*(aq) + 4e¯ How much time (min) is required to collect 12.3 L of oxygen, using a current of 5.42 A, if the gas is collected over water at 22.0°C and the total pressure is 99.7 kPa? Assume that the water is already saturated with oxygen so no more dissolves. Assume Ptotal(gas) P(O2,g) + P(H20,g) and that the correction for column height is negligible. The vapor pressure of water at 22.0°C is 2.643 kPa, F = 96485 C/mol e". and R = 8.314 kPa-Lmol-1.K-1 Enter your final answer for the time required in units of minutes. Include only the numerical answer (no units). Your Answer:
