atm "Synthesis gas" is a mixture of carbon monoxide and water vapor. At high temperature synthesis gas will form carbon dioxide and hydrogen, and in fact this reaction is one of the ways hydrogen is made industrially. A chemical engineer studying this reaction fills a 5.0 L flask with 0.96 atm of carbon monoxide gas and 1.4 atm of water vapor. When the mixture has come to equilibrium he determines that it contains 0.58 atm of carbon monoxide gas, 1.02 atm of water vapor and 0.38 atm of carbon dioxide. The engineer then adds another 0.24 atm of carbon monoxide, and allows the mixture to come to equilibrium again. Calculate the pressure of hydrogen after equilibrium is reached the second time. Round your answer to 2 significant digits. G

A 4.72-g sample of methanol (CH3OH) was placed in an otherwise empty 1.00-L flask and heated to 250.C to vaporize the methanol. Over time, the methanol vapor decomposed by the following reaction: CH3OH(g)CO(g)+2H2(g) After the system has reached equilibrium, a tiny hole is drilled in the side of the flask allowing gaseous compounds to effuse out of the flask. Measurements of the effusing gas show that it contains 33.0 times as much H2(g) as CH3OH(g). Calculate K for this reaction at 250.C.

The boxes shown below represent a set of initial conditions for the reaction: Draw a quantitative molecular picture that shows what this system looks like after the reactants are mixed in one of the boxes and the system reaches equilibrium. Support your answer with calculations.
According to the Resource Conservation and Recovery Act (RCRA), waste material is classified as toxic and must be handled as hazardous if the lead concentration exceeds 5 mg/L. By adding chloride ion, the lead ion will precipitate as PbCl2, which can be separated from the liquid portion. Once the lead has been removed, the rest of the waste can be sent to a conventional waste treatment facility. How many grams of sodium chloride must be added to 500 L of a waste solution to reduce the concentration of the Pb2+ ion from 10 to 5 mg/L?
A gaseous material XY(g) dissociates to some extent to produce X(g) and Y(g): XY(g)X(g)+Y(g) A 2.00-g sample of XY (molar mass = 165 g/mol) is placed in a container with a movable piston at 25C. The pressure is held constant at 0.967 atm. As XY begins to dissociate, the piston moves until 35.0 mole percent of the original XY has dissociated and then remains at a constant position. Assuming ideal behavior, calculate the density of the gas in the container after the piston has stopped moving, and determine the value of K for this reaction of 25C.

The graph below is similar to that of Figure 12.2. If after 100 s have elapsed the partial pressure of N2O4 is increased to 1.0 atm, what will the graph for N2O4 look like beyond 100 s?
For a chemical reaction to take place, some or all chemical bonds in the reactants must break, and new chemical bonds must form among the participating atoms to create the products. Write a simple chemical equation of your own choice, and list the bonds that must be broken and the bonds that must form for the reaction to lake place.
A chemist wants to prepare phosgene, COCl2, by the following reaction: CO(g)+Cl2(g)COCl2(g) He places 4.00 g of chlorine, Cl2, and an equal molar amount of carbon monoxide, CO, into a 10.00-L reaction vessel at 395C. After the reaction comes to equilibrium, he adds another 4.00 g of chlorine to the vessel in order to push the reaction to the right to get more product. What is the partial pressure of phosgene when the reaction again comes to equilibrium? Kc = 1.23 103.
When 1.0 mol each of H2(g) and I2(g) are mixed at a certain high temperature, they react to give a final mixture consisting of 0.5 mol each of H2(g) and I2(g) and 1.0 mol HI(g). Why do you obtain the same final mixture when you bring 2.0 mol HI(g) to the same temperature?
. For the reaction system C(s)+H2O(g)H2(g)+CO(g)which has already reached a state of equilibrium, predict the effect that each of the following changes will have on the position of the equilibrium.

The pressure of hydrogen is increased by injecting an additional mole of hydrogen gas into the reaction vessel. b. Carbon monoxide gas is removed as it forms by use of a chemical absorbent or “scrubber.” c. An additional amount of solid carbon is added to the reaction vessel.
