Question

Now, two reactions are given to Karthik and Arun one each, to find the molecularity of the reaction. Considering that both reactions are elementary.
Reaction (A) is $N H_{4} N O_{2} \to N_{2} + 2 H_{2} O$
Reaction (B) is $2 H I \to H_{2} + I_{2}$
Karthik got the answer as 2 and Arun got answer as 1, which are correct by the way. Can you tell which reactions are given to Karthik and Arun?

Solution

The correct option is B Arun – Reaction A, Karthik Reaction B
Reaction A is $N H_{4} N O_{2} \to 2 H_{2} O$
Here only one molecule $N H_{4} N O_{2}$ is decomposing into products as no other reactants are participating, the molecular is 1.
And for Reaction B
$2 H I \to H_{2} + I_{2}$

2HI molecules colliding each other to form products. As it is given that is an elementary reaction molecularity is 2.

So Karthik got Reaction B and Arun got Reaction A.

Q. Karthik and Arun studying chemical kinetics together. They came around this equation:

N_{2} + 3 H_{2} \to 2 N H_{3}

.
Karthik concluded that the molecularity of the reaction is 4 as one molecule of

N_{2}

is reacting with three molecules of

H_{2}

.
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.
