The methods employed for the determination of equilibrium constant are different for different equilibria depending on the nature of the system and the type of reaction. The task becomes comparatively easy when we can measure some physical property such as vapour density, refractive index, optical rotation, electrical conductivity etc. In simple gaseous dissociation such as N_(2)O_(4) rarr 2NO_(2) . 0.1 mole of N_(2)O_(4(g)) is decomposed under atmospheric condition at 25^(@)C. Degree of dissociation for above problem is :
