### Chemical Kinetics: Determining the Rate Law for a Reaction#### The ReactionThe overall reaction being studied is:\[ 5 \text{Br}^- (\text{aq}) + \text{BrO}_3^- (\text{aq}) + 6\text{H}^+ (\text{aq}) \rightleftharpoons 3 \text{Br}_2 (\text{l}) + 3 \text{H}_2\text{O} (\text{l}) \]This reaction is expected to follow a specific mechanism to reach its final products.#### Proposed Reaction MechanismThe mechanism consists of multiple steps:1. **First Step (Fast Equilibrium)** \[ \text{BrO}_3^- (\text{aq}) + \text{H}^+ (\text{aq}) \rightleftharpoons \text{HBrO}_3 (\text{aq}) \]2. **Second Step (Fast Equilibrium)** \[ \text{HBrO}_3 (\text{aq}) + \text{H}^+ (\text{aq}) \rightleftharpoons \text{H}_2\text{BrO}_3^+ (\text{aq}) \]3. **Third Step (Slow)** \[ \text{Br}^- (\text{aq}) + \text{H}_2\text{BrO}_3^+ (\text{aq}) \rightarrow (\text{Br-BrO}_2) (\text{aq}) + \text{H}_2\text{O} (\text{l}) \]4. **Fourth Step (Fast)** \[ (\text{Br-BrO}_2) (\text{aq}) + 4\text{H}^+ (\text{aq}) + 4\text{Br}^- (\text{aq}) \rightarrow 3\text{Br}_2 (\text{l}) + 3\text{H}_2\text{O} (\text{l}) \]These steps illustrate the detailed progress of the reaction through intermediate states before forming the final products.#### Task: Writing the Rate LawYour task is to write the rate law for this reaction based on the proposed mechanism. To determine the rate law, focus on the slowest step in the mechanism, which is often the rate
