Question

difference between order and molecularityt?​

Answer 1

Answer:

The number of ions or molecules that take part in the rate-determining step is known as molecularity. The sum of powers to which the reactant concentrations are raised in the rate law equation is known as the order of the reaction.

Answer 2

✯ Order ✯

• ⇒ sum of reactant power participating in reaction (rxn)

• ⇒ It is a experimental concept

• ⇒ It can be in fraction

• ⇒ Applicable for elementary or complex reaction

• ⇒ Derived from rate expression

✯ Molecularity ✯

• ⇒ Number of molecules participating in a chemical reaction

• ⇒ It is a theoretical concept

• ⇒ It always be a whole number (1, 2,3 )

• ⇒ Applicable for elementary reaction

• ⇒ Derived from Reaction mechanism
