Help with the question. Thank you Please need steps and the answer Objective Knowledge Check Question 5 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 13.0 °C and constant total pressure. Then, he measures the reaction enthalpy //and reaction entropy4S of the first reaction, and the reaction enthalpy H and reaction free energy G of the second reaction. The results of his measurements are shown in the table. Complete the table. That is, calculate G 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 rew reaction is spontaneous, or neither forward nor reverse reaction is spontaneous because the system is at equilibrium. 2 this reaction 9

Explanation / Answer

Part:a

delta G = delta H - T delta S

             = -1207*103 J - (298 K)(-4312 J/K)

             = +77976 J = 77.96 kJ

The reverse reaction is spontaneous.

Part:b

delta G = delta H - T delta S

-28*103 J = 107*103 J - (298 K)(delta S)

delta S = +453 J/K

This reaction is spontaneous.
