Question

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 ( 116.0{ }^{circ} mathrm{C} ) and constant total pressure. Then, she measures the reaction enthalpy ( Delta H ) and reaction entropy ( Delta S ) of the first reaction, and the reaction enthalpy ( Delta H ) and reaction free energy ( Delta G ) of the second reaction. The results of her measurements are shown in the table. Complete the table. That is, calculate ( Delta G ) for the first reaction and ( Delta S ) 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. egin{tabular}{|c|c|} hline multirow{4}{}{( 2 mathrm{NH}_{3}(g) ightarrow mathrm{N}_{2} mathrm{H}_{4}(g)+mathrm{H}_{2}(g) )} & ( Delta H=188 . mathrm{kJ} ) \ hline & ( Delta S=483 cdot frac{mathrm{J}}{mathrm{K}} ) \ hline & ( Delta G=square mathrm{kJ} ) \ hline & egin{tabular}{l} Which is spontaneous? \ this reaction \ the reverse reaction \ neither end{tabular} \ hline multirow{4}{}{( mathrm{CCl}_{4}(g) ightarrow mathrm{C}(s)+2 mathrm{Cl}_{2}(g) )} & ( Delta H=107 . mathrm{kJ} ) \ hline & ( Delta S=square frac{mathrm{J}}{mathrm{K}} ) \ hline & ( Delta G=19 . mathrm{kJ} ) \ hline & egin{tabular}{l} Which is spontaneous? \ this reaction \ the reverse reaction \ neither end{tabular} \ hline end{tabular}
