Chemistry-Raoult's Law
NEET Chemistry Raoult's Law MCQ Question
Type: MCQ-conceptual-Easy-Class 12
In a solution that exhibits positive deviation from Raoult’s law, what is the expected change in vapor pressure compared to the ideal solution?
A
The vapor pressure is higher than predicted by Raoult's law.
B
The vapor pressure is lower than predicted by Raoult's law.
C
The vapor pressure remains the same as predicted by Raoult's law.
D
The vapor pressure cannot be determined using Raoult's law.
Correct Answer
Option A
Detailed Explanation
A solution showing positive deviation from Raoult's law has weaker solute-solvent interactions, leading to a higher vapor pressure than predicted.
