One gram-mole each of CO2, O2, and N2 are fed to a batch reactor and heated to 3000 K and 5.0 atm. The two reactions given here proceed to equilibrium (also shown are the equilibrium constants at 3000 K) 1. PcoPo0.3272 atm Pco2 PNO0.1222 (po.PN2) Calculate the equilibrium composition (component mole fractions) of the reactor contents. [Suggestion: Express K, and K2 in terms of the extents of the two reactions, ζ, andる. (See Section 4.6d.) Then use Excel's Solver to...
Neon gas is heated from 298 K (1 atm pressure) to 500 K under the following conditions: (a) at constant volume; (b) at constant pressure. In each case, find the molar entropy of the gas in its final state (at 500 K) given that its standard molar entropy at 298 K is 146.33 J/mol K. Assume that neon is ideal gas.
Gasoline enters a combustion chamber, at 1 atm, 298 K and a rate of 0.08 kg/min, where it burns steadily and completely, with 70% excess air that enters the chamber at 1 atm, 200 K. The exit temperature of the combustion products is 800 K. Use the IG mixture model for gases. Represent gasoline with liquid octane. a. Determine the mass flow rate, [kg of air/min], of air. b.

Calculate A, E, μ, cv and S for 1 mole of Kr at 298 K and 1 atm (assuming ideal behavior) Calculate A, E, μ, cv and S for 1 mole of Kr at 298 K and 1 atm (assuming ideal behavior)
Incorrect Question 19 0/8 pts Methane (CH4) at 298 K, 1 atm enters a furnace operating at steady state and burns completely with 220% of theoretical air entering at 400 K, 1 atm. The products of combustion exit at 500 K, 1 atm. The flow rate of the methane is 1.2 kg/min. Kinetic and potential energy effects are negligible and air can be modeled as 21% O2 and 79% N2 on a molar basis. Determine the rate of heat transfer...
In a circular piping, water flows with 2 m/s at 298 K and 1 atm. The piping has a diameter of 0.025 m. Determine the mass transfer coefficient and the Schmidt number of water in the air inside with a length of 3 m.
