Consider a particle that has two states: bonded to a surface, or non-bonded (released). the nonbonded state is higher in energy by an amount ε0. (a) explain how the ability of the particle to bond to the surface contributes to the heat capacity, and why the heat capacity cv = ∂hei ∂t v depends on temperature. (b) compute the heat capacity cv in units of n k if t = 300 k and ε0 = 1.2 kcal/mol, which is about the strength of a weak hydrogen bond in water.

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.
