The synthesis of glucose directly from CO2 and H2O and the synthesis of proteins directly from amino acids are both non-spontaneous processes under standard conditions. Yet these processes must occur for life to exist. In light of the second law of thermodynamics, how can life exist?
Answer to relevant QuestionsA green plant synthesizes glucose by photosynthesis as shown in the reaction 6CO2(g) + 6H2O(l) → C6H12O6(s) + 6O2(g) Animals use glucose as a source of energy: C6H12O6(s) + 6O2(g) → 6CO2(g) + 6H2O(l) If we were to assume ...Predict the sign of ΔSo for each of the following changes. a. b. AgCl(s) → Ag+(aq) + Cl-(aq) c. 2H2(g) + O2(g) → 2H2O(l) d. Na(s) + 1/2 Cl2(g) → NaCl(s) e. HCl(g) → H+(aq) + Cl2(aq) f. KBr(s) → K+(aq) + Br-(aq) The enthalpy of vaporization of ethanol is 38.7 kJ/ mol at its boiling point (78oC). Determine ΔSsys, ΔSsurr, and ΔSuniv when 1.00 mole of ethanol is vaporized at 78oC and 1.00 atm. Acrylonitrile is the starting material used in the manufacture of acrylic fibers (U. S. annual production capacity is more than 2 million pounds). Three industrial processes for the production of acrylonitrile are given ...Using thermodynamic data from Appendix 4, calculate ΔGo at 25oC for the process 2SO2(g) + O2(g) → 2SO3(g) w here all gases are at 1.00 atm pressure. Also calculate ΔGo at 25oC for this same reaction but with all gases at ...
