Raoult's Law and Ideal Solutions
Understand Raoult's law, its application to ideal binary solutions, and the conditions under which solutions behave ideally.
Why this shows up in the exam
You need to apply Raoult's law to calculate vapor pressures and recognize ideal solution behavior in exam problems.
How NEET tests this
Practise it
These are real questions from past NEET papers that test this exact idea.
A solution containing components A and B follows Raoult's law
