- 0.0025 $Ms^{-1}$
- 0.05 $Ms^{-1}$
- 1.0 $Ms^{-1}$
- 4.0 $Ms^{-1}$
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Formula
$Average~Rate = \frac{\Delta [Product]}{\Delta t}$
Step 2: Analysis
- Change in concentration ($\Delta [P]$) = 0.05 M. - Time interval ($\Delta t$) = 20 seconds.
Step 3: Calculation
- $Rate = \frac{0.05}{20} = \frac{5}{2000} = 0.0025~Ms^{-1}$.
Step 4: Conclusion
Hence, the average rate is 0.0025 $Ms^{-1}$. Final Answer: (A)
