Asystem initially containing 2 mol c2h4 and 3 mol 02 undergoes the reactions: c2h4(g) + o2(g) → ((ch2)2)。(g) c2h4 (g) + 302 (g) → 2co2(g) + 2h2o(g) develop expressions for the mole fractions of the reacting species as functions of the reaction coordinates for the two reactions.

Atmospheric air has a temperature (dry bulb) of 80° f and a wet bulb temperature of 60° f when the barometric pressure is 14.696 psia. determine the specific humidity, grains/lb dry air. a. 11.4 c. 55.8 d. 22.5 b. 44.1

Explain in your own word the concept of a solid solution, in alloys, and how it can be created.

An air-conditioning system consists of a heating section and an evaporative cooler. air enters the heating section at 10°c and 70 percent relative humidity at a rate of 30m^3/min, and it leaves the evaporative cooler at 20°c and 60 percent relatively humidity. if the air conditioning system operates at a total pressure of 98 kpa, determine (a) the temperature and relative humidity of the air when it leaves the heating section, (b) the rate of heat transfer in the heating section, and (c) the rate of water added to air in the evaporative cooler
