In a first order reaction, the concentration of the reactant is reduced from 0.6 ~mol ~L ⁻¹ to 0.2 ~mol ~L ⁻¹ in 5 ~min . What is the rate constant of the reaction? ( 3=0.4771)
Options
- A0.219 ~min ⁻¹
- B0.325 ~min ⁻¹
- C0.421 ~min ⁻¹
- D0.522 ~min ⁻¹
Correct answer
A. 0.219 ~min ⁻¹
Step-by-step solution
Given, aligned t & =5 minute A^ & =0.6 ~mol ⁻¹ A & =0.2 ~mol ⁻¹ k & = 2.303 t A^ A & = 2.303 5 0.6 0.2 =0.219 ~min ⁻¹ aligned
