N2(g) + 202(g) → 2NO2(g) A chemist added 0.35 mol of nitrogen gas to 0.45 mol of oxygen gas in 1.0 L container. At equilibrium, the concentration of N2 is 0.30 mol/L. 8. The value of equilibrium concentration of NO2(g) is:

At a particular temperature 8.0 mol NO2 gas is placed in a 1.0-L container. Over time the NO2 decomposes to NO and O2: 2NO2(g) 2 2NO(g) + O2(g) At equilibrium the concentration of NO(g) was found to be 1.8 mol/L. Calculate the value of K for this reaction (using units of mol/L for the concentrations). K =

Calculating an equilibrium constant from a partial equilibrium composition 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 500. mL flask with 3.3 atm of ammonia gas and 0.87 atm of oxygen gas, and when the mixture has come to equilibrium measures the partial pressure of water vapor to be 1.6 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. K = [] p ☐ x10 ☑ 00 18 Α
