Question 3 of 3 questions about the titration of 10.00 mL of 0.2400 M lutidine (C7H13N, pKa = 6.72) with 0.1000 M HCl. What best describes the pH at the end point of the titration?

The Ka for ethylbenzoic acid is 5.6*10-5. What is the pH of a buffer that is 0.72 M ethylbenzoic acid and 0.86 M potassium ethylbenzoate (ethylbenzoate is the conjugate base of ethylbenzoic acid)? Do not type units. Do not use scientific notation.
