Question

Question 8 Filaments of elemental boron might be made by reducing boron trichloride with molecular hydrogen: 2BC13(g) + 3H2(g) - 2B(s) + 6HCl(g) Is the reaction thermodynamically feasible under standard conditions at 298 K? Yes, it is thermodynamically feasible under these conditions. O No, it is not thermodynamically feasible under these conditions. LINK TO TEXT Is the reaction thermodynamically feasible under standard conditions at 995 K? Yes, it is thermodynamically feasible under these conditions. No, it is not thermodynamically feasible under these conditions. LINK TO TEXT Is the reaction thermodynamically feasible at 995 K if each reactant gas is present at p = 5.5 bar and HCl pressure is 0.1 bar? Yes, it is thermodynamically feasible under these conditions. No, it is not thermodynamically feasible under these conditions.

Answer 1

Gibbs free energy is used for checking the feasibility of the reaction if gibbs free energy is negative hence the reaction is feasible and in this case if reaction is taken on standard pressure condition then temperature should be 800-1200 C for reaction to be feasible.

G(p,T)= U+pV-TS

Part A-No it is not thermodynamically feasible under these condition

Part B-No it is not thermodynamically feasible under these condition

Part C-Yes it is thermodynamically feasible under these condition
