Q. Karthik and Arun are studying chemical kinetics together. They came around this equation: N2+3H2→2NH3.
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 are both contradicting each another can you figure out who is correct and who is wrong.
