Another question about gas chromatography, thanks for your help!
Homework Answers
The retention time is inversely proportional to boiling point and area of gas chromatograph is directly proportional to the amount of substance in gas chromatography.
Hence,
There is a lower percentage of compound 2 than 1 in the mixture.
Since retention time depends on lot of factors in gas chromatography
