Calculating dG from dH and dS 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 59.0 °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 the second 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, 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. alo AH = -172. kJ J AS = -420.

(Hint: Since Pis not constant during this process, it doesn't come out of the integral. Use the ideal gas law to find an expression for Pin terms of constants and the integration variable V) D. So what's the work done by the gas on the piston during this process? E. How much heat – if any - was transferred between the gas and surroundings during this process?
