1.	4.5 moles, each of hydrogen and iodine was heated in a sealed 10 L vessel. At equilibrium, 3 moles of HI were found. The equilibrium constant for H_(2) (g) + I_(2) (g) rarr 2HI (g), is
Answer» Solution : at EQULIBRIUM no. of MOLES of HI = 3=2X `implies` X=1.5 `K_(c)=((2x)^(2))/((4.5 - x)^(2))=1`
