1.Liquid acetaldehyde can trimerize into liquid paraldehyde in the presence of a catalyst according to the reaction:

3 CH₃CHO_(l) = [CH₃CHO]_3(l)

At 50 C, an equilibrium solution contains 58% (by mole) acetaldehyde. At 15 C, an equilibrium solution contains 12% (by mole) acetaldehyde.

Estimate the standard Gibbs Free Energy of Reaction and Heat of Reaction (at 25 C), assuming ideal solutions. (You may assume that the heat of reaction is constant with temperature)
