For a first order reaction A → Products, initial concentration of A is 0 . 1   M , which becomes 0 . 001   M after 5 minutes. Rate constant for the reaction in min - 1 is

Step-by-step solution

The integrated rate equation for a first order reaction is given by k = 2 . 303 t log a a - x Where k = Rate   constant a = initial   concentration   of   the   reactants a - x = concentration   of   reactants   left   after   time ,   t . k = 2 . 303 5 log 0 . 1 0 . 001         = 4 . 606 5 = 0 . 9212   min - 1 Hence, the rate constant of the given reaction is 0 . 9212   min - 1
