We are being asked to identify the shift produced in the system with the given concentrations for CO2 and CO. We will use the reaction quotient, Q, to determine if the chemical reaction would be at equilibrium or not. The formula for Q is:

Depending on if Q is greater than or less than K, our reaction will shift to attain equilibrium by reaching the equilibrium constant K:

Problem Details

For the reaction below Kc = 168

C(s) + CO2(g) ⇌ 2CO(g)

A mixture contains some C(s), [CO] = 0.50 M and [CO 2] = 0.75 M. Therefore the system will

a) Shift to produce more C (s) and CO2 (g) because Q < K.

b) Shift to produce more CO because Q < K.

c) Shift to produce more C (s) and CO2 (g) because Q > K.

d) Shift to produce more CO because Q > K.

e) The system is already in equilibrium
