A chemical engineer is studying the two reactions shown in the table below.In each case, she fills a reaction vessel with some mixture of the reactants and products at a constant temperature of 95.0 °C and constant total pressure.Then, she measures the reaction enthalpy AH and reaction entropy AS of the first reaction, and the reaction enthalpy AH and reaction free energy AG of thesecond reaction. The results of her 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, underthe conditions the engineer has set up, the reaction is spontaneous, the reverse reaction is spontaneous, or neither forward nor reverse reaction is spontaneousbecause the system is at equilibrium.AH- 484. kJAS - 1379.
