A) \[3\times {{10}^{-5}}m{{s}^{-1}}\]
B) \[3\times {{10}^{-6}}m{{s}^{-1}}\]
C) \[3\times {{10}^{-8}}m{{s}^{-1}}\]
D) \[3\times {{10}^{-7}}m{{s}^{-1}}\]
Correct Answer: D
Solution :
Given : Rate constant of the first order reaction \[(K)=3\times {{10}^{-6}}\]per sec and initial concentration \[[A]=0.10M\]. We know that initial rate constant \[K[A]=3\times {{10}^{-6}}\times 0.10=3\times {{10}^{-7}}m{{s}^{-1}}\].
