Which of the following reactions are spontaneous (favorable)?

Question

A. DHAP ---> glyceraldehyde - 3 - phosphate ΔG=3.8 kJ/mol
B. C2H4+H2 ----> C2H6 ΔG=-150.97kJ/mol
C. C4H4O5 ---> C4H2O4+H2O ΔG=3.1 kJ/mol
D. L-malata + NAD + ---> oxalocacetate + NADH+H^+ ΔG=29.7 kJ/mol
E. glutamate + NAD^+ H2O ---> NH4^+ a-ketoglutarate+NADH+H^+ ΔG=3.7 kcal/mol
F. C6H13O9P+ATP ---> C6H14O12P2+ADP ΔG=-14.2 kJ/mol

Answer 1

To be spontaneous dG must be - (that's negative).
