This question is about the following reaction:

9.20 g of ethanol are mixed with 12.00 g of ethanoic acid in an inert solvent. The total volume of solution is 250 cm³. The mixture is left to equilibrate for several days. At equilibrium 70% of the reactants are converted to products.

a. What is the concentration of each reactant at the start?

b. What is the concentration of each reactant at equilibrium?

c. What is the concentration of each product at equilibrium?

d. i. Write the equilibrium expression for this reaction.

ii. Calculate the value of K_c for the reaction.

iii. Explain why there are no units for K_c for this reaction.

e. What will happen to the numerical value of K_c if 100 cm³ of water is added to the equilibrium mixture?

f. What will happen to the yield of ethyl ethanoate if 100 cm³ of water is added to the equilibrium mixture? Explain your answer.
