Relation Between vapour density and degree of dissociation : Theory and Numericals:

 

(1) Ammonium carbamate when heated to 200 °C gives a mixture of NH3​ and CO2​ vapour with a density of 13. What is the degree of dissociation of ammonium carbamate?

(2) The observed molecular weight of N 2​O4​ is 80 g mol^−1 at 350 K. The percentage of dissociation of N2​O4​ (g) at 350 K is ?

(3) If PCl5 is 80% dissociated at 523 K, what is the vapour density of the equilibrium mixture at 523 K ?

(4) The vapour density of N2O4 at a certain temperature is 30. What is the percentage dissociation of N2O4 at this temperature?

(5) The vapour density of a mixture containing NO 2​ and N 2​ O 4​ is 38.3 at 27 °C. Calculate the moles of NO2​ in 100 mole mixture.
