Question

Oxygen Supply in Submarines Nuclear submarines can stay under water nearly indefinitely because they can produce their own oxygen by the electrolysis of water. How many liters of O2 at 298 K and 1.00 bar are produced in 3.00 hr in an electrolytic cell operating at a current of 0.0400 A?

Answer 1

0.025 L

Step-by-step explanation:

The production of oxygen in the electrolysis of water is;

4OH^-(aq) -----> 2H2O(l) + O2(g) + 4e

Since 1 F = 96500C

molar volume of a gas = 22.4 L

From the reaction equation;

4 * 96500 C yields 22.4 L of oxygen

(3 * 60 * 60 * 0.0400) C yields (3 * 60 * 60 * 0.0400) * 22.4/4 * 96500

= 9676.8/386000

= 0.025 L
