1.	In the disociation of HI, 20 % HI is dissociated at equilibrium at a certain temperature. Calculate (K_(p)) for the decomposition reaction, HI (g) hArr 1/2 H_(2) (g) + 1/2 I_(2) (g).
Answer» Solution :` {:(,HI,hArr,1/2H^(2),+,1/2I_(2)),("INITIAL",1 "mole",,0,,0),(" AT. eqm.",1-020=080 " mole",,010 " mole",,010 " mole"):}` `K_(c) = ((01)^(1//2)(01)^(1//2))/(080)=0125, K_(p)=K_(c) = 0*055`
