1.	In a gas phase reaction , the decomposition of PCl_(3)takes place at 273^(@)C and 1 atmosphere pressure.It percentage degree of dissociation is 40 per cent . Assuming that all gases in the reaction behave ideally, calculatethe density of the equilibrium mixture. [atomic weight of phosphorus =3 and chlorine=35.5]
Answer» Solution :(i) determination of total number of MOLES (reactions-products) at equilibrium (ii) 3.08 g/L (iii) calculation of the number of moles of the reactants and products PRESENT in the equilibrium mixture (iv) calculation of weight of mixture (v) calculation of VOLUME OFTHE mixture of STP (vi) calculation of volume of equilibrium mixture at the given temperature and pressure (vii) calculation of DENSITY
