Question
**Title: Understanding First Order Reactions**

**4b) Reaction Dynamics**

**Consider the addition reaction A + B → C.**

- **Symbols:** 
  - Circle = A
  - Square = B
  - Triangle = C
- **Rate Law:** Rate = k[B]

**First Order Reactions:**

**Task:** Complete the following pictures and explain your reasoning.

**Diagram Explanation:**

1. **Initial State (Time = 0s):**
   - Three diagrams show a combination of circles (A) and squares (B) within a container. No triangles (C) are present at this stage.

2. **Intermediate State (Time = 100s):**
   - The diagram should begin to show a decrease in the number of squares (B), replaced by triangles (C), indicating the formation of product C as B is consumed over time. The number of circles (A) remains unchanged.

3. **Final State (Time = 200s):**
   - The diagram should depict further decrease in squares (B) with more triangles (C) appearing. Eventually, if B is entirely consumed, only circles (A) and triangles (C) will remain.

**Explanation:**

This sequence illustrates a first order reaction where the rate of reaction is dependent on the concentration of reactant B. As time progresses, reactant B is consumed, and product C is formed, following the rate law.
