A) 400 s
B) 600 s
C) 800 s
D) 100 s
Correct Answer: B
Solution :
Velocity constant\[=0.693\times {{10}^{-1}}mi{{n}^{-1}}\] \[=\frac{0.693\times {{10}^{-1}}}{60}{{s}^{-1}}\] Initial concentration = 0.2 mol/L This is first order reaction. It does not depend on initial concentration. Half-life\[=\frac{0.693\times 60}{0.693\times {{10}^{-1}}}\] \[=600s\]You need to login to perform this action.
