Time required for completion of 99 . 9 % of first order reaction is ________ times of half life ( t 1 / 2 ) of the reaction

Correct answer

0

Step-by-step solution

For first order reaction: kt = log A 0 A t A 0 = Initial concentration of A. A t = Concentration of A at time t. t 99 . 9 % t 50 % = x = log 100 100 - 99 . 9 log 100 50 = log 100 0 . 1 log 2 = log 1000 log 2 = 3 0 . 3 = 10
