![**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.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F277ae00b-d056-42ed-a729-386f4fca5973%2F553232b4-e764-4c5b-bc56-b5d815d42956%2Fikh8wa1.jpeg&w=3840&q=75)
