Based on the standard free energies of formation, which of the following reactions represent a feasible way to synthesize the product?
A. | N2(g)+2O2(g)→2NO2(g); | ΔG∘f=102.6 kJ/mol |
B. | 2Na(s)+O2(g)→Na2O2(s); | ΔG∘f=−451.0 kJ/mol |
C. | C(s)+2S(s)→CS2(g); | ΔG∘f=67.10 kJ/mol |
D. | Ca(s)+12O2(g)→CaO(s); | ΔG∘f=−604.0 kJ/mol |
Drag the appropriate items to their respective bins.
Bin 1: Feasible synthesis
Bin 2: Not a feasible synthesis
if.. ΔG < 0, the reaction is spontaneous .it
proceed forward.
if.. ΔG >0.. the reaction is not spontaneous .
Bin 1: Feasible synthesis = B and D
Bin 2: Not a feasible synthesis = A and C
