Write a Balanced Half-Reaction for the Reduction of Hydrogen Peroxide

Multiple Choice

Write a balanced half-reaction for the reduction of hydrogen peroxide to water in an acidic solution.

A) 2 H₂O₂( ) → 2 H₂O( ) + O₂(g)
B) 2 H₂O₂( ) + 2e^- → 2 H₂O( ) + O₂(g)
C) H₂O₂( ) + 2 H⁺(aq) + 2 e^- → 2 H₂O( )
D) H₂O₂( ) + 4 H⁺(aq) + 2 e^- → 2 H₂O( ) + H₂(g)
E) H₂O₂( ) + 2 H⁺(aq) + 4 e^- → 2 H₂(g) + O₂(g)
