Question

2NH3(g) + 3O2(g) + 2CH4(g) (1000 deg C*ABOVE ARROW) /Pt-Rh *BELOW ARROW)->2HCN(g) + 6H2O(g)

Used in the industrial production of hydrogen cyanide. Assume that ΔH° and ΔS° are invariant with temperature.

a) Calculate ΔH°

b) Calculate ΔS°

c) Calculate ΔG° at 534°C

d) Are the following 5 statements about this process True or False?

-The equilibrium position for this reaction is further to the right at higher temperatures.
-Thermodynamically, this reaction is spontaneous only below a certain temperature.
-At temperatures significantly lower than 1000°C this reaction is not spontaneous.
-This reaction is endothermic at 1000°C.
-The high temperature required for this process is needed for thermodynamic reasons.
