Consider the following reversible reaction to answer questions 1-4. It is EXOTHERMIC.
2 CO2 (g) = 2 CO (g) + O2 (g)
1. Write the Kexpression for this balanced equation.
2. If, at equilibrium, the concentrations of the reactants and products are as follows:
[CO] = 0.00025 M, [O2] = 0.00050, [CO2] = 0.25 M, calculate the value for Ko
3. Where does the equilibrium lie, towards the products or reactants? How can you know?
4. How would the equilibrium system respond to the following stresses? Towards products,
reactants or no change?
Stress
Shift?
a. Add more CO
