If the vapour pressure of solutions of two liquids are less than those expected ideal solution they are said to have:

When the vapour pressure of solutions of two liquids are less than those expected from idea solutions, they are said to show:

At 40^@C the vapour pressures of pure liquids, benzene and toluene, are 160 mm Hg and 60 mm Hg respectively. At the same temperature, the vapour pressure of an equimolar solution of the two liquids, assuming the ideal solution should be:

At 40^@C , the vapour pressure of pure liquids, benzene and toluene, are 160 mm Hg and 60 mm Hg respectively. At the same temperature, the vapour pressure of an equimolar solution of the two liquids, assuming the ideal solution should be
