Question

A new electrode material is being tested for its ability to selectively reduce oxygen gas to hydrogen peroxide. After running an electrolytic cell using this electrode for 110.0 minutes at a current of 0.150 A, the solution in the cathode compartment is analyzed and is found to contain 2.00 ร— 10-3 mol H2O2. What is the percent yield of H2O2 based on the current passed through the cell (the faradaic yield)?

A.

19.5%

B.

39.0%

โœ“ Correct
C.

78.0%

D.

100%
