Consider the following reaction, and its value of K : 2 HBr(g) + Cl2(g) ? 2 HCl(g) + Br2(g) K = 0.065 a. Sketch the reaction energy diagram for this reaction (reactants on the left, products on the right, and transition state in the middle). b. Compare the amounts of reactants and products that will be present when the system reaches equilibrium. c.What will happen to the amount of Cl2 in the system if HCl is removed from the mixture? d. For this reaction, will the value of DG be positive, negative, or zero?
