Free Energy of Reaction -- Temperature Dependence eu. 1000°C 2NH3(g) + 302(g) + 2CH4(9) DIDA → 2HCN(9) + 6H20(9) 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 AHºf and sº are for 25°C. For the purposes of this question assume that AH° and ASº are invariant with temperature. This is not actually true but would generally be a reasonable approximation over "small"...

The Haber-Bosch process is a very important industrial process. In the Haber-Bosch process, hydrogen gas reacts with nitrogen gas to produce ammonia according to the equation 3H2(g)+N2(g)→2NH3(g)3H2(g)+N2(g)→2NH3(g) The ammonia produced in the Haber-Bosch process has a wide range of uses, from fertilizer to pharmaceuticals. However, the production of ammonia is difficult, resulting in lower yields than those predicted from the chemical equation. 1.36 g H2 is allowed to react with 9.75 g N2, producing 1.75 g NH3 What is the...
