FREE Expert Solution

We’re being asked to identify the effect of the changes for the given reaction:

 

2 CO(g)+O2(g) ↔ 2 CO2(g)


According to Le Chatelier’s Principle, if a system (chemical reaction) is at equilibrium and we disturb it, then the system will readjust to maintain its equilibrium state.


1. How will increasing the concentration of CO shift the equilibrium?

  • CO → reactant
  • Adding reactant will favor the forward direction. 


The equilibrium shifts A) to the right

2. How will increasing the concentration of CO2 shift the equilibrium?

  •  CO2 → product
  • Adding product will favor the reverse direction. 

The equilibrium shifts B) to the left
