Determine whether ∆H is equal to, greater than, or less than ∆U for the following reactions. Keep in
mind that “greater than” means more positive or less negative, and “less than” means less positive or
more negative. Assume that the only significant change in volume during a reaction at constant pressure
is that associated with changes in the amounts of gases:
(a) The complete combustion of one mole of 1–butanol (l):

(b) The complete combustion of one mole of glucose, C6H12O6 (s):

(c) The decomposition of solid ammonium nitrate to produce liquid water and gaseous dinitrogen monoxide:
