Consider the reaction: 2NOBr(g) ⇌ 2NO(g) + Br2(g)The Kc value for this reaction at a certain temperature is 0.045. A catalyst is added to the reaction mixture that increases the rate of the forward and reverse reactions to the same extent. What effect will this catalyst have on the equilibrium position of the reaction mixture? Justify your answer using calculations.

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.
