Which of the following statements is/are incorrect regarding order of a reaction?

Answer»

Order of a reaction may be zero, integer or fractional.
For an elementary PROCESS order of the reaction is NEVER fractional.
The order of an elementary step is not equal to its molecularity.
For the chemical equation `N_2+3H_2rarr2NH_3` the order of reaction is 4

Solution : RATE law expression or no other experimental information has been given, order can.t be predicted. Actually order of reaction is conditional with PRESSURE as 0 or 1.
In fact, the order of an elementary step is ALWAYS equal to its molecularity
