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...
A diatomic gas is at a pressure of 100 kPa, 500 cm3 and 20 ° C (point A), it is carried through the following processes. • Compresses adiabatically with a compression ratio equal to 6 (ie VA / VB = 6). • Then it is heated at constant volume until reaching 1000 K. • Then it expands adiabatically until it reaches the original volume. • Finally it is cooled in a constant volume until reaching the original state. Calculate cycle...

A frictionless piston-cylinder device contains 0.2 kg of air at 100 kPa and 27°C. The air is now compressed slowly according to the relation P Vk = constant, where k = 1.4, until it reaches a final temperature of 77°C. Sketch the P-V diagram of the process with respect to the relevant constant temperature lines, and indicate the work done on this diagram. Using the basic definition of boundary work done determine the boundary work done during the process [-7.18...
