A) \[2\times {{10}^{4}}{{s}^{-1}}\]
B) \[3.45\times {{10}^{-5}}{{s}^{-1}}\]
C) \[1.386\times {{10}^{-4}}{{s}^{-1}}\]
D) \[2\times {{10}^{-4}}{{s}^{-1}}\]
Correct Answer: C
Solution :
For first order reaction, Rate constant, \[k=\frac{2.303}{t}\log \frac{a}{a-x}\] \[\Rightarrow \] \[k=\frac{2.303}{2\times {{10}^{4}}}\log \frac{800}{50}\] \[=1.386\times {{10}^{-4}}{{s}^{-1}}\]You need to login to perform this action.
