■ The disorder in a solid is greater than that in a liquid. ( ✓ or X ) ■ The tendency of a process to occur naturally is called equilibrium. (✓ or X ) ▪ A spontaneous change happens unidirectional or in one way. For a reverse change to occur, work always has to be done. (✓ or X) ■ For a spontaneous change to occur, time is not a factor. A spontaneous reaction can be a rapid or very slow reaction. (✓or X ) ■ If the system is not in the equilibrium, a spontaneous change is unavoidable. The change will continue until the system reaches the state of equilibrium. (✓or X ) ■ Thermal heat transfers between cold and hot reservoirs in both directions. (✓ or X ) ■ Absolute zero kelvin is attainable. (✓or X)

A chemical engineer is studying the two reactions shown in the table below. In each case, he fills a reaction vessel with some mixture of the reactants and products at a constant temperature of 105.0 °C and constant total pressure. Then, he measures the reaction enthalpy AH and reaction entropy AS of the first reaction, and the reaction enthalpy AH and reaction free energy AG of the second reaction. The results of his measurements are shown in the table. Complete the table. That is, calculate AG for the first reaction and AS for the second. (Round your answer to zero decimal places.) Then, decide whether, under the conditions the engineer has set up, the reaction is spontaneous, the reverse reaction is spontaneous, or neither forward nor reverse reaction is spontaneous because the system is at equilibrium.
