A) 2.303 s
B) 23.03 s
C) 230.23 s
D) 2303 s
Correct Answer: C
Solution :
\[k=3.01\times {{10}^{-3}}{{s}^{-1}}\] \[{{t}_{1/2}}=?\] \[k=\frac{0.693}{{{t}_{1/2}}}\] (tor a first order reaction) \[\therefore \] \[{{t}_{1/2}}=\frac{0.693}{k}\] \[=\frac{0.693}{3.01\times {{10}^{-3}}}\] \[=230.23\,s\]You need to login to perform this action.
