Consider the Following Mechanism for the Oxidation of Bromide Ions

question 12

Multiple Choice

Consider the following mechanism for the oxidation of bromide ions by hydrogen peroxide in aqueous acid solution. H⁺ + H₂O₂ H₂O⁺-OH (rapid equilibrium)
H₂O⁺-OH + Br^- → HOBr + H₂O (slow)
HOBr + H⁺ + Br^- → Br₂ + H₂O (fast)
What is the overall reaction equation for this process?

• A) 2H₂O⁺-OH + 2Br^- → H₂O₂ + Br₂ + 2H₂O
• B) 2H⁺ + 2Br^- + H₂O₂ → Br₂ + 2H₂O
• C) 2H⁺ + H₂O₂ + Br^- + HOBr → H₂O⁺-OH + Br₂ + H₂O
• D) H₂O⁺-OH + Br^- + H⁺ → Br₂ + H₂O
• E) None of these choices are correct.

Variable Overhead Efficiency Variance

The difference between the actual and expected (or standard) variable overhead costs based on the actual production hours.

Standard Activity

A benchmark or norm for measuring performance or efficiency, often used in costing and budgeting processes.

Predetermined Overhead Rate

A rate used to allocate manufacturing overhead to individual products or job orders, calculated before the production period based on estimated costs and activity levels.

Labor Rate Variance

It's the difference between the actual cost of labor and the budgeted or standard cost of labor.
