The conversion of glucose into lactic acid drives the phosphorylation of 2 moles of ADP to ATP and has a standard free energy of -135 kJ/mol.
C6H12O6 + 2 HPO4 + 2 ADP + 2 H+ -->
2CH3CH(OH)COOH + 2 ATP + 2H20
What is the standard free energy for the conversion of glucose into lactic acid:
C6H12O6(aq) --> 2 CH3CH(OH)COOH(aq)
The answer will be in units of kJ.
From what I've read in the textbook, I need to take the formula above and add it together with the value I get from ATP hydrolysis, which is (-30.5). I am stumped what to do next because I know I have to take the number of moles into account, but don't know how to since the book does not cover examples with stoichiometric coefficients.
