< Question 13 of 14 > What is the value of K for this aqueous reaction at 298 K? A+B C+D AG° = 17.59 kJ/mol
Question 6 Not answered Marked out of 1.00 If the above reaction could be done at 3399 K, what would be your estimate for AGº (in kJ) at this elevated temperature? Use AG° =AH° -TAS® and assume AH° and 4Sº are independent of temperature. P Flag question (Theº is included because it is still for standard conditions, that is, 1 atm for gases and 1 molar for concentrations.) Answer: What is Agrº (in kJ) at 2268 K for the following...
Typical Math Problems 1) What is the pH of a buffer solution which is 0.12M in benzoic acid, pKa 4.19, and is 0.11M in sodium benzoate? 2) Find the %-diss of a buffer if the pKa 7.10 and the pH of the buffer is 7.50. 3) A weak monoprotic acid has a pKa 6.15. 50.00 mL of an 0.1250M aqueous solution of this weak acid is titrated with 0.1000M Na0H. a) What is the equivalence point volume and ½ equivalence...

Question two A buffer solution is able to maintain a constant pH when small amounts of acid or base are added to the buffer. Consider what happens when 1 mL of a 5 M solution is added or 0.005 mol of HCl are added to a 100.0 ml solution acetic acid buffer that contains 0.0100 mol of Acetic acid, HC,H,O,, and 0.0100 mol of sodium acetate, NaC,H,O2. The initial concentration of both the acid and the base are 0.0100 mol/0.1000...
