What is the molecularity of the reaction when nh3 decomposes on a platinum surface to nitrogen and hydrogen gas?

Dear Student,

Molecularity of a reaction is the number of reacting species taking part in an elementary reaction, which must collide simultaneously in order to bring about a chemical change. Since here, 2 molecules of NH3 collides for a chemical reaction, therefore molecularity of this reaction is 2.

It should be 2.

2NH3 decomposes to N2 and 3H2. 2 moles of reactants have to collide simultaneously for the reaction to take place. So, the molecularity is 2.
