A sample of pure NO2 is heated to 339 °C at which temperature it partially dissociates according to the equation 2 NO2 (g) 2 NO (g) + O2 (g) At equilibrium the density of the gas mixture is 0.520 g/L at 0.750 atm .

Ammonia has been studied as an alternative "clean" fuel for internal combustion engines, since its reaction with oxygen produces only nitrogen and water vapor, and in the liquid form it is easily transported. An industrial chemist studying this reaction fills a 2.0 L flask with 2.3 atm of ammonia gas and 0.52 atm of oxygen gas, and when the mixture has come to equilibrium measures the partial pressure of nitrogen gas to be 0.24 atm. Calculate the pressure equilibrium constant for the combustion of ammonia at the final temperature of the mixture. Round your answer to 2 significant digits.

A mixture of 1.374 g of H2 and 70.31 g of Br2 is heated in a 2.00 L vessel at 700 K. These substances react according to H2 (g) + Br2 (g) 2HBr (g). At equilibrium, the vessel is found to contain 0.566g of H2. Calculate equilibrium concentrations for H2, Br, and HBr.

At a certain temperature, 0.3011 mol of N₂ and 1.781 mol of H₂ are placed in a 4.00 L container according to the following equation: N₂(g) + 3H2(g) + 2NH3(g) At equilibrium, 0.1401mol of N₂ is present. Calculate the equilibrium constant.

Steam reforming of methane ( CH, ) produces "synthesis gas," a mixture of carbon monoxide gas and hydrogen gas, which Is the starting point for many 4 Important Industrial chemical syntheses. An Industrial chemist studying this reaction fills a 50.0 L tank with 3.7 mol of methane gas and 4.9 mol of water vapor, and when the mixture has come to equilibrium measures the amount of hydrogen gas to be 7.8 mol. Calculate the concentration equilibrium constant for the steam reforming of methane at the final temperature of the mixture. Round your answer to 2 significant digits.
