A student ran the following reaction in the laboratory at 1080 K: 2SO3(g) 2SO2(g) + O2(g) When she introduced SO3(g) at a pressure of 0.948 atm into a 1.00 L evacuated container, she found the equilibrium partial pressure of SO3(g) to be 0.369 atm. Calculate the equilibrium constant, Kp, she obtained for this reaction. Kp =

Answer asap need by wednesday morning explain how a buffer works, using an ethanoic acid/sodium ethanoate system including how the system resists changes in ph upon addition of a small amount of base and upon addition of a small amount of acid respectively. include the following calculations in your i. calculate the ph of a solution made by mixing 25cm3 0.1m ch3cooh and 40cm3 0.1m ch3coo-na+. [ka = 1.74 x 10-5 m] ii. calculate the ph following the addition of a 10cm3 portion of 0.08 m naoh to 500cm3 of this buffer solution. iii. calculate the ph following the addition of a 10cm3 portion of 0.08 m hcl to 200cm3 of the original buffer solution.
