- The reaction in (C --> B + A) is favorable at low temperatures only and the reaction in (B + 2C --> D) is favorable at all temperatures. What does this imply for the sign of the entropy change of each reaction? Suggest one possible phase of matter for each of the species (A, B, C, and D) consistent with both of these entropy changes C --> B + A ΔH= -730kJ/mol B + 2C --> D ΔH= -185 kJ/molarrow_forward16. Answer question in pic :)arrow_forwardA 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 144.0°C and constant total pressure. Then, he measures the reaction enthalpy ΔH and reaction entropy ΔS of the first reaction, and the reaction enthalpy ΔH and reaction free energy ΔG of the second reaction. The results of his measurements are shown in the table. Complete the table. That is, calculate ΔG for the first reaction and ΔS 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. →+C3H8g5O2g+3CO2g4H2Ol =ΔH−2220.kJ =ΔS−5322.JK =ΔGkJ Which is spontaneous? this reaction the…arrow_forward
- Consider the following reaction at 25 °C: 5 SO3(g) + 2 NH3(g) → 2 NO(g) + 5 SO2(g) + 3 H20(g) If AH° = 42.4 kJ./mol and AS° = 562.3 J/mol•K, estimate the temperature at which this reaction would be at equilibrium assuming that enthalpy and entropy are independent of temperature. %3D %3Darrow_forwardIce cubes at 0°C are poured into a glass that initially contains 150 g of liquid water at 20°C. The contents of the glass are gently stirred. After a short time, some of the ice melts, and the liquid cools to 0°C. No appreciable heat exchange occurs between matter inside the glass with matter outside the glass during this process. (a) Calculate the entropy change of the universe during the process. Use only the following data: the constant pressure heat capacity of liquid water is approximately 4.18 J/(g K) over the temper- ature range of interest. You may further presume that the density of water is constant over the temperature range. (b) If the same process were performed reversibly, how much useful work would be obtained from it? Any required heat exchange to achieve the same final state reversibly should be with matter outside the glass, which are at 20°C.arrow_forwardFor each of the following reactions determine if the change in entropy was positive or negative:A) Water at 40°C → Water at 25°CB) 2NO2(g) → N2O4(g)C) CH3OH (l) → CH3OH (g)D) PbCl2(s) → PbCl2(aq)arrow_forward
