Order of Reaction Chemistry Notes

Order of Reaction :

→ “The number of molecules of reactants taking part in a reaction in which measurable change in concentration takes place and which determines the rate of reaction, is called order of reaction.”
OR
“The sum of powers of all concentration terms in rate law expression of a reaction is called order of reaction.” The order of reaction may be 0, 1, 2, 3 or fractional. Let, a chemical reaction is as follows:
aA + bB + cC → P
Then rate of reaction (r) k[A]m [B]n [C]l
then order of reaction = m + n + l
