What is the effect of a catalyst on the equilibrium position of a reaction in which there are unequal numbers of gaseous reactants and gaseous products? Use the chemical equation for the reaction, the initial concentrations of the reactants and products, and the equilibrium constant (Kc) to determine the changes in reaction rate, the equilibrium concentrations of the reactants and products, and the new value of Kc when a catalyst is introduced.
