Assume that the constant pressure heat capacity, C p , of a solid is a linear function

Question:

Assume that the constant pressure heat capacity, C_p, of a solid is a linear function of temperature of the form C_p = aT, where a is a constant. Starting from the expressions below for S° and ΔH°, show that S°/ΔH° = 2/(298.15 K) = 0.00671 K^-1, a claim made in Are You Wondering 13-3.

S = 298.15 K T - dT AH = 298.15 K JOK CpdT
