The enthalpy and free energy values are zero why isn t the entropy value also zero 2 The vast majority of compounds in a table of thermodynamic data have a negative value for the standard molar free energy of formation Why 3 Predict the sign of the entropy change for the reaction below Briefly justify your answer Ssurr gt 0 and its magnitude is gt Ssys In other words the system loses entropy but the surroundings gain entropy and the gain by the surroundings outweighs the loss by the system e an error has been made as Ssys gt 0 by necessity for a spontaneous process FREE ENERGY AND CALCULATING G FOR REACTIONS Math 21
Answer is D 6 When 1 5 kg of an ideal gas specific heat at constant volume 0 8216 kJ kg K is heated 215 at constant volume to a final temperature of 425 176 C the total entropy increase is 0 4386 kJ K The initial temperature of the gas is most nearly 200 176 C Calculate the standard enthalpy change entropy change and free energy change at 2980C for each of the following reactions by using data in the Appendix in the back of your book

ENTROPY and GIBBS FREE ENERGY Entropy is the degree of randomness in a substance The symbol for change in entropy is S Solids are very ordered and have low entropy Liquids and aqueous ions have more entropy because they move about more freely and gases have an even larger amount of entropy Chapter 20 Entropy and the Second Law of Thermodynamics The Conservation of Energy law allows energy to flow bi directionally between its various forms For example in a pendulum energy continually goes to from kinetic energy and potential energy Entropy is different No conservation law the entropy change S associated with an
