Question

An equilibrium mixture in a vessel of capacity 100 litre contain 1 mol N₂, 2 mol O₂ and 3 mol NO. Number of moles of O₂ to be added so that at new equilibrium the conc. of NO is found to be 0.04 mol/lit.:

Accepted Answer

N2 (g) + O2 (g) 2NO (g)1mole 2mole 3moleKC = .Let a mole of O2 is added, Then,N2 (g) + O2 (g) 2NO (g)1mole 2mole 3molet = 0 1 (2 + a) 3(1 -x) (2 + a)-x (3 + 2x)[NO] = = 0.04 ; (3 + 2x) = 4.2x = 1, x = 0.5.KC = KC = = = [1.5 + a]7.11 = 1.5 + a .a = = 5.61
