23) Consider the following system at equilibrium. 2CO(g) + O2(g) <----> 2CO2(g) a) How will increasing the concentration of CO shift the equilibrium? To the right To the left No effect b) How will increasing the concentration of CO2 shift the equilibrium? To the right To the left No effect c) How will decreasing the the volume of the container shift the equilibrium? To the right To the left No effect

Solutions

Expert Solution

According to Le Chatelier's principle, if a constraint such as the change in temperature, pressure or concentration is applied to a system in equilibrium, the equilibrium will shift in such a way so as to minimize the effect of the constraint.

2CO(g) + O₂(g) 2CO₂(g)

Here, from three moles of gaseous reactants, two moles of the product is formed

Therefore

a) How will increasing the concentration of CO shift the equilibrium?

To the right

Explanation

The equilibrium will shift right to decrease the concentration of CO

b) How will increasing the concentration of CO₂ shift the equilibrium?

To the left

Explanation

The equilibrium will shift left to decrease the concentration of CO₂

c) How will decreasing the volume of the container shift the equilibrium?

To the right

Explanation

Decreasing the volume will decrease the pressure. The equilibrium will shift right to the lower number of gaseous moles to decrease the pressure
