Question

What is the molecularity and order of the following reaction if rate law is, rate = k[O₃][O] respectively.

\[\ce{O_{3(g)} + O_{(g)} -> 2O_{2(g)}}\]

विकल्प

• 3 and 1

• 3 and 2

• 4 and 2

• 2 and 2

Answer 1

2 and 2

Explanation:

\[\ce{O_{3(g)} + O_{(g)} -> 2O_{2(g)}}\]

1. rate = k[O₃][O]
   ∴ Order of reaction = 2
2. Molecularity (No. of reactant molecules taking part in reaction) = 2
