A) \[3\times {{10}^{-6}}m{{s}^{-1}}\]
B) \[3\times {{10}^{-8}}m{{s}^{-1}}\]
C) \[3\times {{10}^{-7}}m{{s}^{-1}}\]
D) \[3\times {{10}^{-9}}m{{s}^{-1}}\]
Correct Answer: C
Solution :
Key Idea: For first order reaction rate \[=k\] [concentration] \[k=3\times {{10}^{-6}}\] per second concentration = 0.1 M rate \[=3\times {{10}^{-6}}\times 0.1\] \[=3\times {{10}^{-7}}m{{s}^{-1}}\]
