Free Energy of Reaction -- Temperature Dependence 2NH3(g) + 30₂(g) + 2CH(g) 1000°C 2HCN(g) + 6H₂O(g) Pt-Rh The above reaction is used in the industrial production of hydrogen cyanide. Consider the relevant thermodynamic data from the appendices of your text. (The tabulated values AH, and sº are for 25°C. For the purposes of this question assume that AH and AS° are invariant with temperature. This is not actually true but would generally be a reasonable approximation over "small" temperature ranges.) Calculate AH° for this equation. -939.8 kJ 1 pts You are correct. Your receipt no. is 152-6870 Calculate AS for this equation. 165 J/K 1 pts You are correct. Your receipt no. is 152-7365 Previous Tries You are correct. Your receipt no. is 152-3405 Previous Tries Calculate AG at 25°C, for this equation. -989.0 kJ 1 pts Previous Tries Are the following statements about this process True or False? True This reaction is exothermic at room temperature. True The equilibrium position for this reaction is further to the right at lower temperatures. Truc At temperatures significantly lower than 1000°C this reaction is spontaneous. True Thermodynamically, this reaction is spontaneous only above a certain temperature. False The high temperature required for this process is needed for thermodynamic reasons. Le Chatelier's principle?
