Question

So is this reaction spontaneous only at lowtemperatures??? Hydrogen cyanide, which is used to makeLuciteÔ and PlexiglasÔ, ismanufactured by the reaction: 2 CH4(g) + 2NH3(g) + 3 O2(g)-> 2 HCN(g) + 6H2O(g). Is this reaction spontaneous at alltemperatures, spontaneous only at low temperatures, or spontaneousonly at high temperatures? Support your answer. (ForHCN(g), DH°f = +135 kJ/mol, S° =201.7 J/K×mol.) So is this reaction spontaneous only at lowtemperatures???

Explanation / Answer

You know that H is positive as well as S. When thishappens the process is spontaneous at high temperatures(TS>H) and nonspontaneous at low temperatures(TS
