The separation factor for two compounds in gas chromatography is 1.022 on a column with a plate height of 0.375 mm. The retention factor for compound 1 is 4.85. a) Find the retention factor for compound 2 b) What length of column will separate the compounds with a resolution of 1.3? c) The retention time for air [tm] is 1.00 minute. If the plate number is the same for both compounds, find [tr] and w1/2 for each peak. d) If the volume ratio of the stationary phase to mobile phase is 0.25, find the distribution constant for compound 1.

I don't understand how you calculated the w1/2 for part c... where did the 5.54 come from?
And can you answer the last part of the question->
d) If the volume ratio of the stationary phase to mobile phase is 0.25, find the distribution constant for compound 1.
