4. Ten molecules of XY react according to the following equation: XY ↔ X + YKc = 1.1 x 10-1 at 125 C Delta H = -24.5 kJ/mol rxn a.In the boxes like the ones shown here, sketch the reactants and products as they would appear when equilibrium has been reached. Assume that the two boxes represent the same reaction chamber. b. A catalyst is added to the reaction. a.How will the concentrations of the reactants and products at equilibrium change? Explain your reasoning. b. How will the addition of a catalyst affect the enthalpy of the reaction? Explain your reasoning. c.The temperature of the reaction is decreased from 125 oC to 25 oC. In the boxes like the ones shown here, draw a possible new molecular diagram to represent any changes that would occur in concentrations. As in (a), the two boxes represent the same reaction chamber. d. Will the equilibrium constant value increase, decrease, or remain the same when the temperature is decreased? Explain your reasoning. e. How will lowering the temperature affect the enthalpy of the reaction? Explain your reasoning.
