Question
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 72.0 °C and constant total pressure. Then, he measures the reaction enthalpy A/ and
reaction entropy AS of the first reaction, and the reaction enthalpy A/ 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.
