In photosynthesis, plants form glucose (C6H12O6) and oxygen from carbon dioxide and water. Part A Write a balanced equation for photosynthesis. 6CO2 + 6H2O → C6H12O6 + 6O2 Part B Calculate ΔH°rxn at 15 °C. Express your answer in units of kilojoules. Part C Calculate ΔS°rxn at 15 °C. Express your answer in joules per kelvin. Part D Calculate ΔG°rxn at 15 °C. Express your answer in kilojoules. Part E Is photosynthesis spontaneous?

Part A If ΔH = -50.0 kJ and ΔS = -0.300 kJ/K, the reaction is spontaneous below a certain temperature. Calculate that temperature. Express your answer numerically in kelvins. Part B Consider the following reaction: C2H4(g) + H2(g) → C2H6(g) ΔH = -137.5 kJ; ΔS = -120.5 J/K Calculate ΔG at 25°C and determine whether the reaction is spontaneous. Express the free energy change in joules to four significant figures. Part C Calculate ΔSrxn° for the reaction: 2NO(g) + O2(g) → 2NO2(g) The following table gives some entropy values: Substance S° (J/mol·K) NO2 240.0 O2 205.2 NO 210.8
