- Actually, the carbon in CO2(g) is thermodynamically unstable with respect to the carbon in calcium carbonate(limestone). Verify this by determining the standardGibbs free energy change for the reaction of lime,CaO(s), with CO2(g) to make CaCO3(s).arrow_forwardConsider the reaction NH4+(aq) H+(aq)+NH3(aq) Use G f for NH3(aq) at 25C=26.7 kJ/mol and the appropriate tables to calculate (a) G at 25C (b) Ka at 25Carrow_forwardCalculate E°, G°, and K at 25°C for the reaction 3Mn2+(aq)+2MnO4(aq)+2H2O5MnO2(s)+4H+(aq)arrow_forward
- Calculate E°, G°, and K at 25°C for the reaction 3MnO4(aq)+4H+(aq)+Cl2(g)2Mn2+(aq)+2ClO3(aq)+2H2Oarrow_forwardCalculate an equilibrium constant from a standard free energy at 25 ᴼC. The reaction is:½ H2(g) + ½ I2(s) ⇆ HI(g).arrow_forwardConsider the following reaction at 100.0 °C: Al(s) + NaOH(aq) + H20(l) ⇄ Na[Al(OH)4](aq) + H2(g) A) Write a balanced equilibrium quotient (Qc) for the following reaction. B) If the pressure of this reaction is increased, which direction will the equilibrium shift? Why?arrow_forward
- Consider the reactions in the table. (a) Write the equilibrium constant in terms of activities for the chemical reaction of fire extinguishers: 2NaHCO3 (s) ↔ Na2CO3 (s) + CO2 (g) + H2O (g) ΔrH = 135.54 KJ (b) At 300 K the equilibrium constant is 3.95x10-6 for the reaction in (a), what is ΔrGo? (c) State in words: what happens to the equilibrium when temperature is increased? Then, verify by finding K for the reaction in (a) at 420 K.arrow_forwardAssuming that neither standard enthalpy changes of formations (∆Hof) nor standard molar entropies (So) depend upon temperature, estimate using the Table of Thermodynamic Data : (a) the standard Gibbs free energy change for the reaction that forms rhombic sulfur at 600 K, and (b) the temperature (in oC) at which reaction will stop formation of products: 2H2S(g) + SO2(g) → 3S(rhombic, s) + 2H2O(g) Round off your answers to the nearest integer. Report the temperature in oC. and enter them with correct units: (a)∆Gorxn = (b) T =arrow_forward
