Using these graphs and the equation Go-dHo-Taso, determine the change of enthalpy and the change of entropy for each compound AHO 4S (kJ/mol K) Compound Equation from Graph (kJ/mol) 2- butanone Propyl acetate 033 24-y 245 .0336 1-2-pentanone 2.18224, 432 3. Using the information acquired in the above question, calculate G° at 25°C for each test Of the three test substances investigated, rank them according to increasing number of carbon atoms. Generate a plot of G(kJ/mol) at 25°C vs. Number of Carbon Atoms.

Solution

Since gibbs free energy is negative for the spontaneous reaction.

All the reaction mentioned here is exothermic and thus spontaneous.

gibbs free energy = change in enthapy - temperature * change in entropy.

The case where both enthalpy and entropy become negative, this reaction is exothermic and spontaneous at low temperature. This case applies on all the reaction mentioned below.
