A chemical reaction has reached equilibrium when: O the concentrations of reactants and products are equal, O the rate of the forward reaction equals the rate of the reverse reaction, O all reactants have been converted to products, O all products have been removed from the reaction mixture. D Question 4 1 pts Consider the following equilibrium mixture in a closed system: H2O(g) + CO(g) = Hz(s) + CO2(g). Explain what would happen to the equilibrium upon the addition of carbon monoxide gas? O The addition of carbon monoxide gas would disrupt the equilibrium causing it to shift towards the left which would result in more reactants being produced until equilibrium is achieved. O The addition of carbon monoxide gas would not disrupt the equilibrium, so nothing would happen. O The addition of carbon monoxide gas would disrupt the equilibrium causing it to shift towards the right which would result in more products being produced until equilibrium is achieved.
