Find the percentage of unreacted reactant for zero order reaction in 90 second having rate constant 1 ~mol dm ⁻³ ~s ⁻¹ .

Options

  1. A5 %
  2. B10 %
  3. C15 %
  4. D20 %

Correct answer

B. 10 %

Step-by-step solution

The rate constant of zero order reaction is given by equation k = [ A ]₀-[ A ]_ t t Let [ A ]₀=100 % array ll & 1 ~mol dm ⁻³ ~s ⁻¹= 100-[ A ]_ t 90 & [ ~A ]_ t =100-90=10 % array
