10. Entropy can be calculated by a relationship proposed by Ludwig Boltzmann:52S = InWwhere k = 1.38 x 10 23 J/K (Boltzmannconstant) and W is the number of ways a certain state can beobtained. (This equation is so important that it is engraved on Boltzmannstombstone, see below.)

A chemicai 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 42.0 °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.
