The Gas OF₂ Can Be Produced from the Electrolysis of an Aqueous

question 140

Multiple Choice

The gas OF₂ can be produced from the electrolysis of an aqueous solution of KF,as shown in the equation below. OF₂(g) + 2 H⁺(aq) + 4 e^- → H₂O(l) + 2 F^-(aq) E° = +2.15 V
Using the given standard reduction potential,calculate the amount of OF₂ that is produced,and the electrode at which the OF₂ is produced,upon the passage of 0.240 faradays through an aqueous KF solution.

• A)3.24 g of OF₂ at the anode
• B)13.0 g of OF₂ at the anode
• C)3.24 g of OF₂ at the cathode
• D)13.0 g of OF₂ at the cathode
