gasoline. Diesel can be approximated at $C_{12}{H}_{23}.$ The combustion chamber is the control volume. There are $5\mathrm{.}9k\frac{o}{h}r$ of diesel tuel entering the chamber along with air. Also entering the chamber is $3000$ molhr of air that contains $79$ mol $86K$ and $21$ molys O$2.$ Assume that the reaction goes to completion and that nitregen deesn't react.

a$.(3)$When fuel is burned in the presence of oxygen. the resultant products are $C{O}_2$ and $H_{2}O.$ White out the combustion chemical cquation and balance is$.$ Make sure that the coefificient in front of the diesel is $1($frections are ol$).$

b$.(3)$ in: for molar flowrate since we are now doing chemical reactions.

c$.($B$)$ Write out the molar balance for each species.

d$.(3)$ Write out a SPICEY table below. Assume complete reaction for the finlting reactant.

e$.(3)$ Which one is the limiling reactent?

f$.(3)$ Is the engine burning lean $($excess oxygen$)$ or rich $($excess fuelly?

g$.(3)$ What is the extent of reaction?

h$.(3)$ Calculate the mol fraction of CO$2$ leaving the chamber.

i$.(3)$ Are the number of moles entering the chamber equal to the number of moles leaving? Why or why nol?

j$.(6)$ Use Excel to calculate the mass of each species entering and exiting the reactor. Does the total mass in equal the total mass out?
