A) 6.92 minute
B) 100 minutes
C) \[0.693\times {{10}^{-3}}\]minute
D) \[0.693\times {{10}^{-2}}\]minute
Correct Answer: B
Solution :
For 1st order reaction, \[\text{rate}=K\times [A]\] \[\therefore \] \[0.693\times {{10}^{-2}}=K\times 1\] or \[K=0.693\times {{10}^{-2}}{{\min }^{-1}}\] We know that, \[{{t}_{1/2}}=\frac{0.693}{K}=\frac{0.693}{0.693\times {{10}^{-2}}}\] = 100 minuteYou need to login to perform this action.
