Write a Hess’s law problem that solves the following equation; 4C(s) + 5 H2(g) + ½ O2(g) → C4H9OH(g) ΔH° = ??? kJ Normally an “overall” equation is given that has an unknown value of Heat of Reaction. There would be 2-5 additional equations listed that when combined in a certain order, would yield the overall equation and allow the Heat of Reaction to be determined. Your task is to find these 2-5 equations and use them to solve for the Heat of Reaction for the formation of butanol. Please watch the states of the chemicals as the values of H change for each phase. You can assume this is n-butanol or 1-butanol if that is helpful.
