3.Ethanol Production.Ethylenc gas, C2H4(g) and steam at 320°C and 1 atm pressure are fed to a reaction process as an equimolarmixture. The reaction goes by:C,H4(g) + H20G) → CzH;0H)The process goes to completion and produces 1 mol of liquid ethanol C,H50Hy that leaves the reactor at 25°C.What is the heat, Q (kJ), associated with the process per mole of ethanol produced?Note: You must provide a full material balance for the process for full credit.Note: You must draw a hypothetical path for the process for full credit.LP Data from Appendix CRC2H4(g)H20(g)C2H50H(9)A1.4243.4703.51814.394 X 1031.450 X 10320.001 X 10-3-4.392 X 10-6.002 X 10-60.121 X 10
