N-hexane is burned with excess air to yield the following gas product (on a dry-basis): 7.0 mol% co2, 2.0 mol% co, 0.5 mol% c6h14 with the remaining being 02 and n2. the stack gas emerges at 1 atm (a) draw and label a flow chart (2 marks). (b) balance the reaction(s) (2 marks) (c) calculate the percentage conversion of hexane (5 marks) (d) calculate the percentage excess air fed to the burner (3 marks) (e) calculate the dew point (tdp) of the stack gas, assuming water is the only condensable species
