Question
**1. In the reaction**

\[ \text{C}_3\text{H}_7\text{Br(aq)} + \text{H}_2\text{O(l)} \rightarrow \text{C}_3\text{H}_7\text{OH(aq)} + \text{HBr(aq)} \]

The concentration of the reactant changes from 0.0671 M at 125 seconds to 0.0549 M at 315 seconds. Calculate the average rate of decomposition.

*(Note: Average rate = Change in concentration / Change in time)*

---

**2. Write the rate for the following reaction in terms of:**

\[ 2\text{HCl(g)} \rightarrow \text{H}_2\text{(g)} + \text{Cl}_2\text{(g)} \]

(a) \[\text{HCl}\]

(b) \[\text{H}_2\]

---

**3.** After experimentally determining the order of this reaction, it was found to be 2nd order in \[\text{HCl(g)}\]. Write the rate law.
