Consider the following chemical system at equilibrium.

CO(g)
+ H₂O(g)
+ heat  CO₂
(g)
+ H₂
(g)

For each of the following adjustments of conditions, indicate the effect (shifts left, shifts right, or no effect) on the position of equilibrium.

a) Adding H₂
to the equilibrium mixture

b) Decreasing the size of the reaction container
