A) 400 sec
B) 600 sec
C) 800 sec
D) 1200 sec
Correct Answer: B
Solution :
The unit of rate constant shows that reaction is of first order. For first order reaction, half life is independent of initial conc. of the reactant. Thus, \[{{t}_{1/2}}=\frac{0.693}{0.69\times {{10}^{-1}}}=\frac{0.693\times 60}{0.69\times {{10}^{-1}}}=600\,\sec \]You need to login to perform this action.
