Question

$2N{H}_3\left(g\right)\to N_2\left(g\right)+3H_2\left(g\right)$
Above equilibrium is established by taking initially only ammonia gas in the container. Find the degree of dissociation of ammonia gas in 34 g of the mixture if molar mass of the mixture is $\frac{34}{3}g.$

• A. 0.25
• B. 0.5
• C. 0.75
• D. 0.33

Answer 1

The correct option is B 0.5

$\frac{M_{N{H}_3}}{M_{mix}}=1+\alpha$

$\Rightarrow \frac{17}{34/3}=1+\alpha$

$=0.5$
