In a gas chromatography experiment, a mixture of two compounds (a and b) was separated for analysis. a chart recorder that fed paper at a constant rate of 100 mm. per minute was used to record the chromatogram, and a mark was made on the chart at the time the sample was injected. the first peak on the chromatogram corresponds to compound a, and that peak was observed at a distance of 5.19 cm from the sample injection point, and it had a height of 3.05 cm and a width at half-height of 1.16 cm. the peak corresponding to b was observed at a distance of 8.23 cm from the injection point, and it had a height of 4 cm and a width at half-height of 1.9 cm. what was the retention time for compound b (in seconds)? (enter your answer as a number only.)

Sulfur dioxide and oxygen react to form sulfur trioxide during one of the key steps in sulfuric acid synthesis. an industrial chemist studying this reaction fills a 25.0l tank with 4.5 mol of sulfur dioxide gas and 4.5 mol of oxygen gas at 30.Β°c. he then raises the temperature, and when the mixture has come to equilibrium measures the amount of sulfur trioxide gas to be 1.4 mol. calculate the concentration equilibrium constant for the reaction of sulfur dioxide and oxygen at the final temperature of the mixture. round your answer to 2 significant digits.
