3 2A(g) + Blg) - (g) When 1.0 mol A and 0.75 mol B to were allowed to achieve equilibrium
at 65°c. in a container of a 1dm3 capacity, the equilibrum mixture was
found to contain 0.7 mol A and 0.6mol B. calculate kc at 65°c.

Answer asap need to be answered 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.
