Find the percentage of unreacted reactant for zero order reaction in 90 second having rate constant 1 ~mol dm ⁻³ ~s ⁻¹ .
Options
- A5 %
- B10 %
- C15 %
- 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
