The product gas from the combustion of n-pentane with excess air was reported to have a dry basis composition of 0.270 mole% pentane, 5.3% oxygen, 9.1% carbon dioxide, and the balance nitrogen. (a) determine whether the data are correct, assuming a basis of 100 moles of dry product gas. (b) the analysis of the combustion products was performed again and yielded the following results: 0.304 mole% pentane, 5.9% oxygen, 10.2% carbon dioxide, and the balance nitrogen. determine the percent excess air fed to the reactor and the fractional conversion of pentane
