Question: In an electrolysis experiment a current of 0.5 amperes flowing for 20 min (1200s) liberates 69.6mL of gas at the cathode and 23.3mL at the anode. You may assume that both gases are at STP (T = 272.3K, P = 1.013 × 105 Pa).

a. How many moles of gas molecules are produced at the cathode?

b. How many electrons were needed to form one molecule of gas at the cathode?

c. Which of the following chemical reactions is consistent with the information given above?

2H₂O → 2H₂ + O₂

2CO₂→ 2CO + O₂

2N₂O₃→ 2N₂ + 3O₂

2NH₃ → N₂+ 3H₂
