Which of the following statement is wrong about molecularity of a reaction? |
It is number of molecules of reactant taking part in a single step chemical reaction. It is calculated from reaction mechanism. It may have a fractional value. It depends on the rate determining step. |
It may have a fractional value. |
Molecularity is defined as the number of reactant species which collide simultaneously to form products. It is defined only for elementary (one step) reactions. It is always a positive integer. Higher molecularity (>3) are rare because chances of collisions of more than three molecules at a time are very less. |
