Simple distillation and gas chromatrography'

Question 1

what comprises one theoretical plate

Answer 1

one vaporization phase and one condensation phase

Question 2

if you have a larger difference in boiling points, will you need more or less theoretical plate?

Answer 2

a larger difference in boiling points requires less theoretical plates

Question 3

what affect does increasing the number of theoretical plates have on enrichment

Answer 3

it increases enrichment

Question 4

what is the mobile phase in gas chromatography

Answer 4

the inert carrier gas

Question 5

what is the stationary phase in gas chromatography

Answer 5

the column the sample passes through

Question 6

what is on the x axis in gas chromatography

Answer 6

time

Question 7

describe how how a gas chromatograph actually measures compounds

Answer 7

it measures how much time it takes different compounds to travel through the column and pass by the detector

Question 8

what does it mean for a peak to be towards the left side of a chromatograph

Answer 8

it traveled through the column faster, so it vaporized easier and spent more time in gas phase

Question 9

what does the area under a curve on a chromatograph represent

Answer 9

the compound’s concentration
