Practise This Question

Karthik and Arun studying chemical kinetics together. They came around this equation: N2+3H22NH3.
Karthik concluded that the molecularity of the reaction is 4 as one  molecule of N2 is reacting with three  molecules of H2.
But Arun said that molecularity of 4 is very unlikely as the probability of 4 molecules colliding simultaneously is almost zero.
As they both contradicting one another can you tell who is correct and who is wrong.
