$(50$ pts$.)$ Please write and solve a combustion reaction problem in which three fuel materials are combusted. You

must provide a process specification for oxygen or air being fed in excess. At least one of the three fuels must

undergo both complete and incomplete combustion, and at least one of the fuels must not be fully consumed. A

value for the input flow rate of the fuel stream should be provided in the problem statement. The input flow rate of

the air$/$oxygen stream cannot be specified. The problem solution must determine the molar flow rate of the product

stream and its composition on both a wet basis and a dry basis. The solution should show that the process has

exactly zero degrees of freedom. Material balances must be in the form of either atomic species balances or extent

of reaction equations. A completely labeled flow diagram should be part of the solution.

Both a typed $($or handwritten$)$ solution and an Excel summary should be provided for the problem. The typed $($or

handwritten$)$ solution should include a list of all equations a written based on the flow diagram before beginning to

solve, followed by the appropriate solution steps. The template and instructions for the Excel summary are provided

below.

Options for reactants to be combusted $($choose $3)$:

Hydrogen $(H_2),$ Methane $(C{H}_4),$ Ethane $(C_2{H}_6),$ Propane $(C_3{H}_8),$ Butane $(C_4{H}_{10}),$ Pentane $(C_5{H}_{12}),$ Hexane $(C_6{H}_{14}),$

Heptane $(C_7{H}_{16}),$ Octane $(C_8{H}_{18}).$

Excel Summary format for Questions $1$ and $2$:

Your Excel summary should be provided in the format shown below. List the names of your unknown variables in Column

A$.$ List the corresponding solved numerical value for each unknown in Column B$.$ Leave Column C blank. In Column D$,$ list

the equations in their original form as written based on the flow diagram before beginning to solve. For Question $1,$ list

all $10$ possible material balances, even if you didn't use all the equations in the solution. List the equations used to solve

first, then list any other material balances. Also in Column $D,$ after listing the material balance equations, list any process

specification equations. In Column E$,$ calculate the left$-$hand side of the equation shown in Column $D$; if the left$-$hand side

is just a number, write it in Column E$.$ In Column F$,$ calculate the right$-$hand side of the equation shown in Column D; if

the right$-$hand side is just a number, write it in Column F$.$ In Column G$,$ if an equation was not used in the problem

solution, enter $"N"$ for that equation; if an equation was used in the solution leave blank. Example unknowns, values, and

equations are shown to illustrate what goes where. Replace with your own. All calculations necessary to solve the

problem must be performed in the Excel spreadsheet using the built$-$in math capabilities.
