If the concentrations of the reactants are changed so that the rate of the forward reaction is doubled, how will this affect the equilibrium concentrations of the four gases?

O The ratio of the concentrations expressed by Kc stays the same.
O Doubling the rate of reaction will cause the concentration of the products to double.
O Doubling the rate of reaction will cause the ratio of the concentration of products to the concentration of reactants to double.
O The change in the rate of reaction will cause the equilibrium concentrations of the four gases to decrease.
