Oct 13, 2025 by miodeya.com 146 views

Introduction

In this article, we will examine a proposed mechanism for a chemical reaction and determine whether it is consistent with the net equation and rate law. The mechanism consists of a single step, where hypochlorite ion (OCl-) reacts with water to form hypochlorous acid (HOCl). We will analyze the mechanism and show that it is consistent with the net equation and rate law.

The Mechanism

The proposed mechanism is as follows:

{ \begin{array}{l} \text{Step 1: } \text{OCl}^- (\text{aq}) + \text{H}_2\text{O} (\text{l}) \rightarrow \text{HOCl} \end{array} }

Net Equation

To determine the net equation, we need to add up the reactants and products of the mechanism. In this case, the reactants are OCl- and H2O, and the product is HOCl. Therefore, the net equation is:

{ \text{OCl}^- (\text{aq}) + \text{H}_2\text{O} (\text{l}) \rightarrow \text{HOCl} }

This net equation is consistent with the proposed mechanism.

Rate Law

To determine the rate law, we need to analyze the rate-determining step. The rate-determining step is the slowest step in the mechanism, and it determines the overall rate of the reaction. In this case, the rate-determining step is Step 1, where OCl- reacts with H2O to form HOCl.

The rate law for this step can be written as:

{ \text{rate} = k [\text{OCl}^-] [\text{H}_2\text{O}] }

where k is the rate constant, and [OCl-] and [H2O] are the concentrations of OCl- and H2O, respectively.

Consistency with the Net Equation

The rate law is consistent with the net equation because the rate law includes the reactants of the net equation (OCl- and H2O) and their concentrations.

Consistency with the Rate Law

The mechanism is also consistent with the rate law because the rate-determining step (Step 1) has a rate law that matches the overall rate law.

Conclusion

In conclusion, the proposed mechanism is consistent with the net equation and rate law. The net equation is:

{ \text{OCl}^- (\text{aq}) + \text{H}_2\text{O} (\text{l}) \rightarrow \text{HOCl} }

and the rate law is:

{ \text{rate} = k [\text{OCl}^-] [\text{H}_2\text{O}] }

The rate-determining step is Step 1, where OCl- reacts with H2O to form HOCl.

Rate-Determining Step

The rate-determining step is the slowest step in the mechanism, and it determines the overall rate of the reaction. In this case, the rate-determining step is Step 1, where OCl- reacts with H2O to form HOCl.

Implications

The fact that the mechanism is consistent with the net equation and rate law has important implications for our understanding of the reaction. It suggests that the reaction occurs through a single step, where OCl- reacts with H2O to form HOCl. This has implications for the design of experiments and the interpretation of data.

Future Directions

Future research could focus on determining the rate constant (k) and the concentrations of OCl- and H2O. This would allow us to better understand the reaction and make more accurate predictions about its behavior.
