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.
