A) \[2.46\times {{10}^{2}}\text{ }mi{{n}^{-1}}\]
B) \[4.62\times {{10}^{-2}}{{\min }^{-1}}\]
C) \[6.74\times {{10}^{-2}}{{\min }^{-1}}\]
D) \[7.18\times {{10}^{2}}{{\min }^{-1}}\]
Correct Answer: B
Solution :
For 1st order reaction Rate constant \[(k)=\frac{0.693}{{{t}_{1/2}}}\] \[=\frac{0.693}{15}=4.62\times {{10}^{-2}}{{\min }^{-1}}\]
