For each event stated below, indicate how the concentration of each species in the chemical equation then change to reach equilibrium. Click in the blue box below to toggle the relative change in concentration (up=increases, down=decreases leave the box blank for no change). 2CO(g)+O2(g) 2CO2 (g) increasing the concentration of CO increasing the concentration of CO2 decreasing the the volume of the system

To analyze how the concentrations of each species will change when the system is disturbed and moves to re-establish equilibrium, we need to apply Le Chatelier's Principle, which states that if an external change is applied to a system at equilibrium, the system will adjust itself in such a way as to counteract that change.

Here is how each event affects the system: 1. Increasing the concentration of CO (carbon monoxide): When you increase the concentration of CO, the system will respond by consuming more of the additional CO to produce more CO2 (carbon dioxide), thus shifting the equilibrium to the right. This will cause the concentration of CO to ultimately decrease and the concentration of CO2 to increase.

2. Increasing the concentration of CO2: If the concentration of CO2 is increased, the system will respond by trying to reduce this added product. The equilibrium will be shifted to the left, resulting in the consumption of CO2 to produce more CO and O2. Consequently, the concentration of CO2 will decrease, while the concentrations of CO and O2 will increase.

3. Decreasing the volume of the system: Decreasing the volume of the system increases the pressure inside the container. Because there are 3 moles of gas reacting to form 2 moles of gas (2CO + O2 → 2CO2), a decrease in volume will drive the equilibrium to the side with fewer moles of gas to reduce the pressure, which is the right side of the equation. Thus, the concentration of CO and O2 will decrease, while the concentration of CO2 will increase.

Summarizing the changes in concentrations:

- Increasing the concentration of CO: [CO] will initially increase but then decrease as it forms more CO2, [O2] will decrease, and [CO2] will increase. - Increasing the concentration of CO2: [CO2] will initially increase but then decrease as it reacts to form more CO and O2, [CO] and [O2] will increase. - Decreasing the volume of the system: [CO] and [O2] will decrease, and [CO2] will increase.
