For a first order reaction, the concentration of reactant was reduced from 0.03 ~mol ~L ⁻¹ to 0.02 ~mol ~L ⁻¹ in 25 min . What is its rate (in . mol L ⁻¹, s⁻¹ ) ?

Options

  1. A6.667 10⁻⁶
  2. B4 10⁻⁴
  3. C6.667 10⁻⁴
  4. D4 10⁻⁶

Correct answer

A. 6.667 10⁻⁶

Step-by-step solution

Given :- Time =25 60 sec .=25 ~min Concentration of Reactant =0.03 ~mol ~L ⁻¹ Concentration of product =0.02 ~mol ~L ⁻¹ Rate = [ R ] t [-(0.02-0.03)] 25 60 6.67 10⁻⁶ ~mol ~L ⁻¹ ~S ⁻¹
