chapter 6. CHEMICAL KINETICS class 12 chemistry textbook solution
3. Answer the following in brief.
iii. A reaction takes place in two steps,
1. NO(g) + Cl2(g) →NOCl2(g)
2. NOCl2(g) + NO(g) →2NOCl(g)
a. Write the overall reaction. b. Identify reaction intermediate. c. What is the molecularity of each step?
Answer:-
i. The overall reaction is: \[2NO_{(g)} + Cl_{2(g)} \rightarrow 2NOCl_{(g)}\]
ii. In the first step, NOCl2 is formed, and in the second step, it is consumed. Therefore, it acts as a reaction intermediate.
iii. The molecularity of each step is 2 because two reactants are involved in each of the steps.
