Answer 1

Answer:

(A) 7/34

Explanation:

The chemical equation for the given disassociation reaction is -

$2 NH_3$  ⇒ $N_2 + 3H_2$

So, 34 g of NH3 gives 28 g of N2

Now, percentage disassociation = 20 %

So, mass of NH3 that disassociates = 0.2 * 34 g = 6.8 g

So, mass of N2 formed = 28/34 * 6.8 = 5.6 g

Mass of NH3 that remains un- dissociated = 34 g - 6.8 g = 27.2 g

Therefore N2 : NH3 = 5.6/27.2 = 7/34
