Carbon Monoxide and Chlorine Combine in an Equilibrium Reaction to Produce

question 6

Multiple Choice

Carbon monoxide and chlorine combine in an equilibrium reaction to produce the highly toxic product, phosgene (COCl₂) . If the equilibrium constant for this reaction is K_c = 248, predict, if possible, what will happen when the reactants and product are combined with the concentrations shown. [CO] = [Cl₂] = 0.0200 M; [COCl₂] = 0.0992 M

• A) The reaction will proceed to the right.
• B) The reaction will proceed to the left.
• C) The reaction is at equilibrium, and no change in concentrations will occur.
• D) The container volume needs to be specified before a prediction can be made.
• E) The temperature needs to be specified before a prediction can be made.
