Be sure to answer all parts. Consider the c 13 C4H10(g) + 2 (a) Predict the O AS: Feedback Reactions proceed spontaneously in the direction of lowest free energy, G, where AG=AH-TAS. You need to determine whether energy is absorbed or released for the combustion of a gas to determine the sign of the enthalpy change. You must also determine how the number of accessible microstates (entropy) changes when a reaction results in the increase in the number of moles of gas. Ok, got it AH : O (b) Calculate AG at 298 K. -2,969.9 X X
