= -18.3 + 2577.34 ln 1.068 / 0.0144
= -18.3 + 2577 .34 ln 74.16
= -18.3 + 2577 .34 (4.306) = 112079 / 1000 = 11.2079
= + 11.2

Adenosine triphophste, ATP, is used to store energy within biological systems. It releases that energy by losing a terminal phosphate group, Pi, to form adenosine diphophate, ADP, through the hydrolysis reaction. The standard reaction Gibbs energy for hydrolysis of ATP to ADP is + 10 kJ mol at 298K. This assumes that the concentration of hydrogen ions is 1 mol/ L. a) In biochemistry, it is common practice to assume an alternative, and more realistic, standard state for pH=7. What...
