D)+93.7 kJ/mol

Quizplus · Accepted Answer

To find the ∆G°' for the formation of ATP from phosphoenolpyruvate and ADP, we need to reverse the first reaction (which changes the sign of ∆G°') and then add it to the second reaction. Reversing the first reaction gives +31.5 kJ/mol, and adding it to the second reaction's ∆G°' of -62.2 kJ/mol gives -30.7 kJ/mol.
