Q5.
What is the order of a reaction which has a rate expression ; Rate =
Answer : Option A
Explaination / Solution:

Total order of reaction = order wrt to A + order wrt to B.

Q6. Molecularity of a reaction
Answer : Option A
Explaination / Solution:

Molecularity means minimum no. of atoms molecules or ions which undergo collision for conversion of reactant to Product. So it is a whole no. Cannot be fractional or negative.
