Consider the following reactions: (i) 2N2O5 ⇌ 2N2O4 + O2 (ii) NO2 + O3 ⇌ NO2 + O2 (iii) 6CO2+ 6H2O N ⇌ C6H12O6+ 6O2 (iv) (CH3)3 CBr + HOH ⇌ (CH3)3 COH + HBr Which of the following is zero order reaction?
Correct answer: C. III
- A. I
- B. II
- C. III
- D. II and III
Explanation
Order of a reaction is an experimentally determined value. It is zero for reaction III.

About Reaction Kinetics
Reaction kinetics relates reaction rate to concentration, temperature, surface area and catalysts. Questions cover rate laws, reaction order, rate constants, activation energy and the activated complex, including how a catalyst lowers the activation energy without changing the overall energy change or equilibrium position.
