STANDARD Chemistry Ideal and Non-Ideal Solutions MCQ Question

Type: MCQ-conceptual-Medium-Class 12

What are the conditions for an ideal solution which obeys Raoult's law over the entire range of concentration?

A

mixH = 0, ΔmixV = 0, Ptotal = P°AXA + P°BXB

B

mixH = +ve, ΔmixV = 0, Ptotal = P°AXA + P°BXB

C

mixH = 0, ΔmixV = +ve, Ptotal = P°AXA + P°BXB

D

mixH = 0, ΔmixV = 0, Ptotal = P°BXB

Correct Answer

Option A

Detailed Explanation

For an ideal solution ΔH and ΔV for mixing should be zero. Ptotal = PA + PB and A-A, B-B and A-B interactions are nearly same.
