Consider the vapour over an ideal molar liquid mixture of benzene () and toluene () at . Which of th — Solutions and Colligative Properties Chemistry Question

💡 Solution & Explanation

According to Konowaloff's rule, the vapour phase in equilibrium with an ideal liquid solution is always richer in the more volatile component. Since benzene has a higher pure vapour pressure ($12.8 > 3.85$), it is more volatile and dominates the vapour phase.
