Question 4

An equilibrium system is established in the gas phase according to the equation:

NO2(g)+CO(g)⇌NO(g)+CO2(g) \text{NO}_2(g) + \text{CO}(g) \rightleftharpoons \text{NO}(g) + \text{CO}_2(g) NO2​(g)+CO(g)⇌NO(g)+CO2​(g)

Different initial amounts of NO2\text{NO}_2NO2​, CO\text{CO}CO, NO\text{NO}NO, and CO2\text{CO}_2CO2​ are introduced into four identical, separate containers of the same volume at a constant temperature, as detailed in the table below.

ContainerNO2\text{NO}_2NO2​ / molCO\text{CO}CO / molNO\text{NO}NO / molCO2\text{CO}_2CO2​ / mol
A2.02.00.02.0
B0.02.02.02.0
C2.00.02.02.0
D2.02.02.00.0

Which container will contain the largest concentration of CO(g)\text{CO}(g)CO(g) when equilibrium is established?

Container A

Container B

Container C

Container D
