Carbon Monoxide and Chlorine Combine in an Equilibrium Reaction to Produce

question 48

Multiple Choice

Carbon monoxide and chlorine combine in an equilibrium reaction to produce the highly toxic product, phosgene (COCl₂) CO(g) + Cl₂(g)
COCl₂(g)
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] = 0.010 M; [COCl₂] = 0.070 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.
