The value of the equilibrium constant for the following reaction is 16 at a given temperature: CO(g)+ H₂O(g)⇌ CO₂(g)+ H₂(g)If [CO] = 4.0 M, [H₂O] = 4.0 M, [CO₂] = 4.0 M, and [H₂] = 4.0 M, determine if the reaction is at equilibrium. If it is not, in which direction will it proceed to reach equilibrium?

The reaction quotient, Q, is calculated as:Q = [CO2][H2]/[CO][H2O] = (4.0 M)(4.0 M)/(4.0 M)(4.0 M) = 1.0Since Q is not equal to the equilibrium constant, Kc, the reaction is not at equilibrium. The reaction will proceed to the right to reach equilibrium, where Q = Kc = 16.
