Question

differentiate between molecularity and order of reaction with examples
​

Answer 1

Answer:

We define order of reaction as the number of molecules of the reactant whose concentration changes during the chemical change. Molecularity is the number of ions or molecules that take part in the rate-determining step. ... To determine order we should sum up the exponents from the rate law of the equation.

Answer 2

Answer:

molecularity :

1. molecularity is the number of ions or molecules that take part in the rate - determining step .
2. it is always a whole number.
3. the molecularity of the reaction is determining by looking at the reaction mechanism

order :

1. number of molecules of the reactant whose concentration changes during the chemical change.
2. it can either be a whole number or a fraction.
3. the order of the reaction is determined by the experimental methods
