Question

How is the heat of formation related to the stability? Which of the two isomers of butane is more stable at 25°C. (nbutane) = -120 kJ mol-1and ∆Hf (Isobutane) = -129.8 kJ mol-1​

Answer 1

Answer:

Any differences in the heat given off can be used to say that a compound is more stable (it had a lower energy to begin with, so less heat is given off) or less stable (it had a higher energy to begin with, so more heat is given off).
