What is the difference between the order and the molecularity of a reaction?
Answers
Answer:
^_^ not really sure but here um
Explanation:
the molecularity of a reaction represents the number of atoms,molecules or ions that will interfere which each other for the chemical reaction to occurs within a limited time frame
Answer:
Reaction: we should know about reaction if it takes place in a single step than it is elementary reaction. And if a reaction takes place in two or more steps then we say it as a complicated reaction. And this sequence of steps through which a complicated reaction takes place is called reaction – mechanism. Each step in a mechanism is an elementary step reaction.
One simple idea about the molecularity of reaction that we can get is the minimum number of molecules that are required for feasibility of reaction is called Molecularity.
Chemical reaction Molecularity
1 PCl5→PCl3+Cl2 Uni-molecular
2 NO+O3→NO2+O2
Bi-molecular
3 2SO2+O2→2SO3
Tri-molecular
We define order of reaction as the number of molecules of the reactant whose concentration changes during the chemical change.
Molecularity Order
Molecularity is the number of ions or molecules that take part in the rate-determining step. Number of molecules of the reactant whose concentration changes during the chemical change
It is always a whole number It can either be a whole number or a fraction
The molecularity of the reaction is determined by looking at the reaction mechanism The order of the reaction is determined by the experimental methods
It is theoretical concept It is experimental concept
It is meaningful only for simple reactions or individual steps of a complex reaction. It is meaningless for an overall complex reaction. It is meant for the reaction and not for its individual steps
