Type: MCQ-diagram based-Hard-Class 12
Refer to the diagram of a binary solution system. If component 1 is non-volatile and component 2 is volatile with a vapor pressure of 200 Torr in pure form, what is the total vapor pressure of the solution when the mole fraction of component 2 is 0.3?
A
60 Torr
B
140 Torr
C
200 Torr
D
475 Torr
Correct Answer
Option A
Detailed Explanation
Using the formula p_total = x2 * p2^0, where p2^0 is 200 Torr and x2 is 0.3, the total vapor pressure is 60 Torr.
