**Understanding Reaction Mechanisms: The Roles of B and C**In the study of reaction mechanisms, it's crucial to identify the roles of various species involved in the process. Consider the following reaction mechanism for the reaction \( A \rightarrow D \):\[ A + B \rightleftharpoons C + B \]\[ C \rightarrow D \]Based on this mechanism, we need to determine the roles of species B and C. Below is a multiple-choice question designed to test this understanding:1. **Which of the following best describe the roles of B and C in the following mechanism for the reaction \( A \rightarrow D \)?** - \( A + B \rightleftharpoons C + B \) - \( C \rightarrow D \) **Options:** - **A) B and C are catalysts** - **B) C is a catalyst and B is an intermediate** - **C) B is a catalyst and C is an intermediate** - **D) B and C are intermediates**#### Explanation:In the given mechanism:- \( A + B \rightleftharpoons C + B \): This step indicates that B is regenerated after the formation of C. Species that are regenerated in a reaction and appear in the same form at the beginning and end are typically catalysts.- \( C \rightarrow D \): C is used up in the reaction to form D, indicating that C is not regenerated and thus serves as an intermediate in the reaction.**Answer:** C) B is a catalyst and C is an intermediateUnderstanding these roles helps in grasping the overall reaction mechanism, aiding in the prediction and manipulation of chemical processes in both educational and practical applications.

Question

**Understanding Reaction Mechanisms: The Roles of B and C**

In the study of reaction mechanisms, it's crucial to identify the roles of various species involved in the process. Consider the following reaction mechanism for the reaction \( A \rightarrow D \):

\[ A + B \rightleftharpoons C + B \]
\[ C \rightarrow D \]

Based on this mechanism, we need to determine the roles of species B and C. Below is a multiple-choice question designed to test this understanding:

1. **Which of the following best describe the roles of B and C in the following mechanism for the reaction \( A \rightarrow D \)?**

- \( A + B \rightleftharpoons C + B \)
- \( C \rightarrow D \)

**Options:**
- **A) B and C are catalysts**
- **B) C is a catalyst and B is an intermediate**
- **C) B is a catalyst and C is an intermediate**
- **D) B and C are intermediates**

#### Explanation:

In the given mechanism:
- \( A + B \rightleftharpoons C + B \): This step indicates that B is regenerated after the formation of C. Species that are regenerated in a reaction and appear in the same form at the beginning and end are typically catalysts.
- \( C \rightarrow D \): C is used up in the reaction to form D, indicating that C is not regenerated and thus serves as an intermediate in the reaction.

**Answer:** C) B is a catalyst and C is an intermediate

Understanding these roles helps in grasping the overall reaction mechanism, aiding in the prediction and manipulation of chemical processes in both educational and practical applications.
