At a given temperature, total vapour pressure in Torr of a mixture of ...
Given information:
- Total vapor pressure of a mixture of volatile components A and B is given by P = 120 + 75XB, where XB is the mole fraction of component B.

Explanation:
To find the vapor pressure of pure components A and B, we need to consider the limiting cases where the mole fraction of one component is either 0 or 1.

Case 1: Pure Component A
When XB = 0, the mixture contains only component A.
Substituting XB = 0 in the given equation, we get:
P = 120 + 75 * 0
P = 120 Torr

Case 2: Pure Component B
When XB = 1, the mixture contains only component B.
Substituting XB = 1 in the given equation, we get:
P = 120 + 75 * 1
P = 195 Torr

Therefore, the vapor pressure of pure component A is 120 Torr and the vapor pressure of pure component B is 195 Torr.

Conclusion:
The correct answer is option C) 120, 45 Torr, which corresponds to the vapor pressures of pure components A and B, respectively.
