Calculate the time (in hours) it will take to produce 1.50×10³ kg of potassium when a sample of molten KF was subject to electrolysis using a constant current of 2.50×10⁴ A. Determine the volume (in L) of F₂ gas produced at STP.

• A. time = 41.1 hours
  volume of F₂ gas = 4.30×10⁵ L
• B. time = 31.5 hours
  volume of F₂ gas = 2.45×10⁵ L
• C. time = 41.1 hours
  volume of F₂ gas = 3.42×10⁵ L
• D. time = 22.7 hours
  volume of F₂ gas = 5.61×10⁵ L

Answer: (A)
