Nitric Oxide, an Important Pollutant in Air, Is Formed from the Elements

Question 33

Multiple Choice

Nitric oxide, an important pollutant in air, is formed from the elements nitrogen and oxygen at high temperatures, such as those obtained when gasoline burns in an automobile engine. At 2000°C, K for the reaction N2(g) + O2(g) Nitric oxide, an important pollutant in air, is formed from the elements nitrogen and oxygen at high temperatures, such as those obtained when gasoline burns in an automobile engine. At 2000°C, K for the reaction N<sub>2</sub>(g)  + O<sub>2</sub>(g)    2NO(g)  is 0.01. A 1-L container originally holds 0.4 mol of N<sub>2</sub>, 0.1 mol of O<sub>2</sub>, and 0.08 mol of NO. If the volume of the container holding the equilibrium mixture of N<sub>2</sub>, O<sub>2</sub>, and NO is decreased to 0.5 L without changing the quantities of the gases present, how will their concentrations change? A)  The concentrations of N<sub>2</sub> and O<sub>2</sub> will increase, and the concentration of NO will decrease. B)  The concentrations of N<sub>2</sub>, O<sub>2</sub>, and NO will decrease. C)  The concentrations of N<sub>2</sub>, O<sub>2</sub>, and NO will increase. D)  There will be no change in the concentrations of N<sub>2</sub>, O<sub>2</sub>, and NO. E)  The concentration of NO will increase, and the concentrations of N<sub>2</sub> and O<sub>2</sub> will decrease. 2NO(g) is 0.01. A 1-L container originally holds 0.4 mol of N2, 0.1 mol of O2, and 0.08 mol of NO. If the volume of the container holding the equilibrium mixture of N2, O2, and NO is decreased to 0.5 L without changing the quantities of the gases present, how will their concentrations change?


A) The concentrations of N2 and O2 will increase, and the concentration of NO will decrease.
