A → B Reactant Product If formation of compound B follows the first order of kinetics and after 70 minutes the concentration of A was found to be half of its initial concentration. Then the rate constant of the reaction is x × 10 - 6 s - 1 . The value of x is____

Correct answer

0

Step-by-step solution

A → B Reactant Product Since the reaction follows the first order kinetics and after 70 minutes the concentration of A was found to be half of its initial concentration. That means 70 minutes is the half life time for the reaction. And we know that for a first order reaction half life time is given as. t 1 2   =   0 . 693 K K = 0 . 693 t 1 2 = 0 . 693 70 × 60   sec . = 6930 7 × 6 × 10 - 6   sec - 1 =   165   × 10 - 6   sec - 1 So ,   x   = &#160
