For a zero order reaction A product. Conc. of A decreases from 0.8 ~mol dm ⁻³ to 0.2 ~mol dm ⁻³ in 6 minute. What is rate constant of the reaction?
Options
- A0.01 ~mol dm ⁻³ minute ⁻¹
- B1.0 ~mol dm ⁻³ minute ⁻¹
- C0.1 ~mol dm ⁻³ minute ⁻¹
- D1.66 ~mol dm ⁻³ minute ⁻¹
Correct answer
C. 0.1 ~mol dm ⁻³ minute ⁻¹
Step-by-step solution
For a zero order reaction, aligned & k = [ A ]₀-[ A ]_ t t & = (0.8-0.2) mol dm ⁻³ 6 minute & = 0.6 ~mol dm ⁻³ 6 minute & k =0.1 ~mol dm ⁻³ minute ⁻¹ aligned
