Question:

Retention time depends on temperature, T, according to the equation log (a/T) b, where a and b are constants for a specific compound on a specific column. A compound is eluted from a gas chromatography column at an adjusted retention time 15.0 min when the column temperature is 373 K. At 363 K, 20.0 min. Find the parameters a and b and predict at 353 K
