Components of a binarey mixture of two liquids A and B were being separted by distillation. After some time separation of components stopped and composition of vapour phase vecame same as that of liquid phase. Both the components stated coming in the distillate. Explain why this happened ?

Explanation

To explain why the separation of components in a binary mixture of two liquids A and B stops during distillation and why both components start appearing in the distillate, we can break down the explanation into several steps:

### Step 1: Understanding Distillation
Distillation is a separation technique that relies on differences in boiling points of components in a mixture. When a mixture is heated, the component with the lower boiling point vaporizes first, and this vapor can be condensed back into a liquid (distillate).

**Hint:** Recall that distillation separates components based on their boiling points.

### Step 2: Composition Change During Distillation
