Which of the following is pseudo unimolecular reaction?
Options
- A2 H 2 O 2 → 2 H 2 O + O 2
- BC 6 H 5 N 2 C l + H O H → C 6 H 5 O H + N 2 + H C l
- CC H 3 C O O C 2 H 5 + N a O H → C H 3 C O O N a + C 2 H 5 O H
- D2 O 3 + 3 O 2
Correct answer
B. C 6 H 5 N 2 C l + H O H → C 6 H 5 O H + N 2 + H C l
Step-by-step solution
Rate of the following reaction may be gives as C 6 H 5 N 2 C l + H O H → C 6 H 5 O H + N 2 + H C l Rate = k [ C 6 H 5 N 2 C l ] [ H O H ] For hydrolysis, water will be in large excess, therefore, concentration of water will be constant. Rate law may be given as Rate = k ' C 6 H 5 N 2 Cl Reaction is therefore a pseudo unimolecular reaction.
