1.	Consider following figure and answer the questions at the end of it. Figure explains elevation in boiling point when a non-volatile solute is added to a solvent. Variation of vapour pressure with temperature and showing elevation in boiling point. A complex of iron and cyanide ions is 100% ionized at 1m (molal). If its elevation in boiling point is 2.08^(@) (K_(b) = 0.52^(@) mol^(-1) kg) then the complex is
