A Suggested Mechanism for the Decomposition of Peroxide (H₂O₂)is H₂O₂

question 99

Multiple Choice

A suggested mechanism for the decomposition of peroxide (H₂O₂) is H₂O₂ (aq) 2OH (aq)
H₂O₂ (aq) + OH (aq) H₂O (l) + HO₂ (g)
HO₂ (g) + OH (aq) H₂O (l) + O₂ (g)
Which of the following correctly labels the chemical equation for the overall reaction and the reaction intermediates?

• A)Overall reaction = H₂O₂ (aq)H₂O (l)+ O₂ (g),intermediates = HO₂ (aq)+ OH (aq)
• B)Overall reaction = 3H₂O₂ (aq)3H₂O (l)+ O₂ (g),intermediates = OH (aq)
• C)Overall reaction = 2H₂O₂ (aq)2H₂O (l)+ O₂ (g),intermediates = HO₂ (aq)+ OH (aq)
• D)Overall reaction = H₂O₂ + 2OH (aq)+ HO₂ (aq)H₂O (l)+ 2OH (aq)+ O₂ (g)+ HO₂ (aq),intermediates = HO₂ (aq)+ OH (aq)
