Question: A reaction at constant T and P is spontaneous as
A reaction at constant T and P is spontaneous as long as ΔG is negative; that is, reactions always proceed as long as the products have a lower free energy than the reactants. What is so special about equilibrium? Why don’t reactions move away from equilibrium?
Answer to relevant QuestionsΔG predicts spontaneity for a reaction at constant T and P, whereas ΔGo predicts the equilibrium position. Explain what this statement means. Under what conditions can you use ΔGo to determine the spontaneity of a ...One of the reactions that destroys ozone in the upper atmosphere is NO(g) + O3(g) ⇌ NO2(g) + O2(g) Using data from Appendix 4, calculate ΔGo and K (at 298 K) for this reaction. Consider the following reaction at 800. K: N2(g) + 3F2(g) → 2NF3(g) An equilibrium mixture contains the following partial pressures: PN2 = 0.021 atm, PF2 = 0.063 atm, and PNF3 = 0.48 atm. Calculate ΔGo for the reaction at ...At 25.0oC, for the reaction 2NO2(g) ⇌ N2O4(g) the values of ΔHo and ΔSo are –58.03 kJ/ mol and –176.6 J K-1mol-1, respectively. Calculate the value of K at 25.0oC. Assuming ΔHo and ΔSo are temperature independent, ...Consider 1.00 mole of CO2(g) at 300. K and 5.00 atm. The gas expands until the final pressure is 1.00 atm. For each of the following conditions ΔEscribing the expansion, calculate ΔS, ΔSsurr, and ΔSuniv. Cp for CO2 is ...
