Acetylene is produced from methane in the reaction: 2CH4 (g) → C₂H₂ (g) + 3 H₂ (g) An undesired side reaction is the decomposition of acetylene: C₂H₂ (g) → 2 C(s) + H₂ (g) Methane is fed to the reactor at 1500°C at a rate of 10 mol CH4/s. The reaction is carried out isothermally at a constant pressure of 1atm. The fractional conversion of methane is 0.6 and the yield of acetylene is 0.417 mol C₂H₂/mol CH4 consumed. Determine the magnitude and direction of heat transferred for this reaction. Your answer should include the following: Simplify the EB equation for this system. b. Set up an enthalpy table and determine your reference states. C. Used detailed specific enthalpy calculations (I should be able to clearly see how you calculated each of your H; values) to determine the heat flow magnitude (kJ/mol ethanol feed) and direction.
