What is the relationship between the partial vapour pressure of a component and the mole fraction of that component in solution according to Raoult’s law?
What is the relationship between the partial vapour pressure of a component and the mole fraction of that component in solution according to Raoult’s law?
- $p_i = p_i / x_i$
- $p_i = p_i x_i$ (correct)
- $p_i = p_i - x_i$
- $p_i = p_i + x_i$
