Question

Based on the standard free energies of formation, which of the following reactions represent a feasible way to synthesize the product?

A. 2C(s)+H2(g)→C2H2(g); ΔG∘f=209.2 kJ/mol

B. N2(g)+3H2(g)→2NH3(g); ΔG∘f=−33.30 kJ/mol

C. 2C(s)+2H2(g)→C2H4(g); ΔG∘f=68.20 kJ/mol

D. 2CO(g)+O2(g)→2CO2(g); ΔG∘f=−788.0 kJ/mol

Answer 1

ΔG∘f <0   feasible the reactions

ΔG∘f <0 reactions represent a feasible way to synthesize the product

the negative value of ΔG∘f is feasible reactions

B. N2(g)+3H2(g)→2NH3(g); ΔG∘f=−33.30 kJ/mol

D. 2CO(g)+O2(g)→2CO2(g); ΔG∘f=−788.0 kJ/mol
