Consider the reaction below which was carried out at 200.0 K to produce liquid ammonia: N2(g) + 3H2(g) ---> 2NH3() Suppose 37.3 g of N2 gas is mixed with 37.3 g of H2 gas. What is the volume (in units of liters) of gas remaining after the reaction is completed? The remaining gas was measured to have a temperature of 200.0 K and a pressure of 760.0 mmHg? molar mass of N2 = 28.013 g/mol molar mass of H2 = 2.0158 g/mol. Recall: Va (1/P) (at constant T and n) VaT (at constant Pand n) Van(at constant T and P) PV = nRT rate of effusion o 1 atm = 760 torr = 760 mmHg R-8.31446 J - K-1. mol-1 R= 0.0820573L-atm- K-1. mol-1

A chemical engineer must calculate the maximum safe operating temperature of a high-pressure gas reaction vessel. The vessel is a stainless-steel cylinder that measures 21.0 cm wide and 25.2 cm high. The maximum safe pressure inside the vessel has been measured to be 8.80 MPa. For a certain reaction the vessel may contain up to 0.650 kg of carbon dioxide gas. Calculate the maximum safe operating temperature the engineer should recommend for this reaction. Write your answer in degrees Celsius. Round your answer to 3 significant digits. temperature: I °C

Suppose you have 1.25 moles of gaseous napthalene (C10H8) at T = 292 K. What is the average kinetic energy of one molecule of napthalene? (The molar mass of napthalene is 128 g/mol. You may assume that the gas molecules behave ideally.)

Ammonia is among the top ten synthesized compounds. Its many uses include the manufacture of ammonium nitrate and other fertilizers. Ammonia decomposes at high temperatures. In an experiment to explore this behavior, 2.00 moles of gaseous NH3 are sealed in a rigid 1-liter vessel. The vessel is heated at 800 K and some of the NH3 decomposes in the following reaction: 2NH3(g) <--> N2(g)+3H2(g) The system eventually reaches equilibrium and is found to contain 1.74 mole of NH3. What is the value of KC for the decomposition reaction at 800K? What is the value of KP for the decomposition reaction at 800 K?

7. When detern ing the mass of a liquid, ras in a hurry and did not allow enough time for the temperature of the flask to reach the temperature of the boiling water bath. The student recorded the temperature of the gas as 100.0°C when it was only 80.0°C, Is the molar mass calculated by the student higher or lower than the accepted molar mass, or does this error have no effect on the calculated result? Briefly explain your answer # 2/HB Office DEPOTS b) If the student assumed the volume of the flask was 125 mL (as marked by the side of the flask) rather than measuring the volume experimentally, would the unknown's calculated molar mass be too high, too low, or unaffected? Explain. # 2/HB 4
