1.The vapour pressure of the solution of two liquids A (P∘=80 mmP^\circ = 80\,\text{mm}P∘=80mm) and B (P∘=120 mmP^\circ = 120\,\text{mm}P∘=120mm) is found to be 100 mm100\,\text{mm}100mm when XA=0.4X_A = 0.4XA=0.4. The result shows thata.Solution exhibits ideal behaviourb.Solution shows positive deviation from ideal behaviourc.Solution shows negative deviation from ideal behaviourd.Attractive intermolecular forces between A–A in pure liquid A and B–B in pure liquid B are stronger than those between A–B when mixed in solutionLogin to continueOnly logged in users canattempt or see the solution.
