Question

For an ideal binary liquid solution, Raoult law gives the total vapour pressure as

Accepted Answer

C. {'text': 'p_A° × x_A + p_B° × x_B', 'label': 'C'}

1. For an ideal solution, each component obeys Raoult law individually.
2. p_A = p_A° × x_A and p_B = p_B° × x_B.
3. Total vapour pressure p = p_A + p_B = p_A° x_A + p_B° x_B.
4. This is the linear (weighted) sum characteristic of an ideal binary mixture.
