Explanation / Answer

Post one more question to get the remaining answers solution

The B line is known as Dew Point Line

Hence the answer to the first MCQ is Option B

At the feed point, mole fraction of Benzne is 0.70

Mole fraction of Toluene = 1 - mole fraction of Benzene

=> 1 - 0.7

=> 0.3

Hence it will be 0.7 mole of benzene and 0.3 mole of toluene

Hence the correct answer is Option B

The correct answer is 0.5, hence the option will be C
