'Reaction with zero order is possible but zero molecularity is not''.Justify the statement.

Text Solution

Verified by Experts

Molecularity of a reaction is the number of molecules, atoms or ions which collide simultaneously to bring about reaction. So it is always a natural number. Zero molecularity is no possible.
Order is the sum of power of concentration term in rate law. It can be zero.
