In order to obtain a reasonable level of conversion at a commercially acceptable rate, ammonia synthesis reactors operate at pressures of 150 to 300 atm and temperatures of 700 to 750 K. Calculate the equilibrium mole fraction of dinitrogen at 300 atm and 723 K starting from an initial composition of XN2 = 0.25, XH2= 0.75 (Xi is the mole fraction of species i). At 300 atm and 723 K, the equilibrium constant, Ka , is 6.6 X 10^- 3

Solve correctly please need all parts.

An air stream is contaminated by 100 ppm (on a molar basis) of compound X. You wish to remove compound X from the air by condensation. 100 ppm (parts per million) = 0.01 mol% = 10-4 mol fraction. Please mark answers on graph when applicable c) Consider the phase diagram of compound X shown above. Locate the point on the graph that corresponds to 100 molar ppm of compound X in air at 300 K and 1 atm. d) If the contaminated air is cooled at constant pressure (1 atm), at what temperature will compound X start to condense? e) To what temperature must you cool the air (at total pressure of 1 atm) to reduce the contamination level to 10 ppm? f) If the contaminated air is compressed at constant temperature (300 K), at what pressure will compound X start to condense?

1. Water Quality Analysis - A public utility announces the monthly average concentrations of several ionic species in the drinking water. The list is given below (atomic weights are given in parentheses): Calcium (40) = 8.6 mg/L Magnesium (24)=0.77 mg/L Potassium (39) = 0.64 mg/L Sodium (23) = 3.7 mg/L a) What is the ratio of [HCO3]/[CO3²] in this water Chloride (35.5) -3.0 mg/L Fluoride (19)- 0.84 mg/L Sulfate (S-32; O=16)= 3.4 mg/L pH=8.46

The rate of decomposition of SO, Cl2 according to the reaction so,Cl, (s) → SO2(g) + Cl2 (g) can be followed by monitoring the total pressure in the reaction vessel. Consider the following data. Time (s) Total Pressure (torr) 491.7 180.9 548.7 434.0 618.4 605.7 659.1 916.7 721.7 1233.3 773.0 1504.9 809.0 2015.2 860.7 Convert these total pressures into changes in the pressure of the SO, Cl, manipulate the data as needed, and then use a graphing calculator or spreadsheet to plot the data to determine the order of the reaction and the rate constant. What is the order of the reaction? O zero-order O frst-order O second-order Determine the value and unit of the rate constant. (Enter an unrounded value.) k =
