1.	A closed vessel of known volume containing known amount of ideal gaseous substance 'A' was observed for variation of pressure with temperature . The expected graph was to be like as in (i) However actual observations reveal the graph to be like (ii). The deviation was attributed to polymerisation of gas molecules as nA(g)hArrA_(B)(g).If it is known that the above reaction given only 50% yield Find the value of n to which the gas A is being polymerised into
Answer» Solution :`nArArrA_(N) V=` constant `t=t_(eq)` moles `a_(0)-a_(0)alpha (a_(0)alpha)/(n)` ideal gases:- PV-nRT `P=(nR)/(V)(t^(@)+273)` `PV_(s)t(.^(@)C) y=mx+C`where `m=(nR)/(V)` `(m_("actual"))/(m_("theoriticl"))=(n_("actual"))/(n_("theortical"))=(a_(0)a_(0)alpha+(a_(0)alpha)/(n))/(a_(0))=(1.0375)/(1.66)=(1)/(1.6)` `(0.5xx1.6)/(n)=0.2` n=4
