Suppose a 500. mL flask is filled with 1.4 mol of N2 and 0.70 mol of NO. This reaction becomes possible: N2(g) + O2(g) = 2NO (g) Complete the table below, so that it lists the initial molarity of each compound, the change in molarity of each compound due to the reaction, and the equilibrium molarity of each compound after the reaction has come to equilibrium. Use r to stand for the unknown change in the molarity of N2. You can leave out the M symbol for molarity.

Suppose a 500. mL flask is filled with 1.6 mol of NO2 and 0.60 mol of NO. This reaction becomes possible: 2NO2(g)=2NO(g) + O2(g) Complete the table below, so that it lists the initial molarity of each compound, the change in molarity of each compound due to the reaction, and the equilibrium molarity of each compound after the reaction has come to equilibrium. Use x to stand for the unknown change in the molarity of O2. You can leave out the M symbol for molarity. NO2 NO 02 initial change equilibrium ☐ ☐ X ☐ ☑

Nitrogen dioxide is one of the many oxides of nitrogen (often collectively called "NOx") that are of interest to atmospheric chemistry. It can react with itself to form another form of NOx, dinitrogen tetroxide. A chemical engineer studying this reaction fills a 125 L tank with 45. mol of nitrogen dioxide gas. When the mixture has come to equilibrium he determines that it contains 12. mol of nitrogen dioxide gas. The engineer then adds another 11. mol of nitrogen dioxide, and allows the mixture to come to equilibrium again. Calculate the moles of dinitrogen tetroxide after equilibrium is reached the second time. Round your answer to 2 significant digits. | mol x10
