Consider the following equilibrium mixture in a closed system: H2O(g) + CO(g) = H2(g) + CO2(g). Explain what would happen to the equilibrium upon the addition of hydrogen gas? The addition of hydrogen gas would disrupt the equilibrium causing it to shift towards the left which would result in more reactants being produced until equilibrium is achieved. The addition of hydrogen gas would disrupt the equilibrium causing it to shift towards the right which would result in more CO2 being...
