Below is a graph of the data collected during the experiment:### Graph Description- **Title:** Concentration of \(\text{NH}_4\text{OH}\) over Time- **X-axis (Horizontal):** Time (\( t \)) in seconds (s)- **Y-axis (Vertical):** Concentration of \(\text{NH}_4\text{OH}\) in molarity (M)### Detailed Explanation of the Graph- **Initial Concentration:** At \( t = 0 \) s, the concentration of \(\text{NH}_4\text{OH}\) is approximately 1.5 M.- **Decay Over Time:** As time progresses, the concentration of \(\text{NH}_4\text{OH}\) decreases. The curve shows a rapid decline initially.- **Approaching Zero:** By \( t = 5 \) s, the concentration of \(\text{NH}_4\text{OH}\) approaches nearly 0 M, indicating that most of the \(\text{NH}_4\text{OH}\) has reacted.Use this graph to answer the following questions:---**Note:** This educational content is a study resource for understanding the rate of chemical reactions using data visualization techniques.

From graph we can see that initial concentration of NH4OH is 1 M.
