The Standard Free Energy Change $\Delta$ G'°) for ATP Hydrolysis Is -30

question 55

Short Answer

The standard free energy change ( $\Delta$ G'°) for ATP hydrolysis is -30.5 kJ/mol. ATP, ADP, and P_i are mixed together at initial concentrations of 1 M of each, then left alone until the reaction ADP + P_i $\rightarrow$ ATP has come to equilibrium. For each species (i.e., ATP, ADP, and P_i), indicate whether the concentration will be equal to 1 M, less than 1 M, or greater than 1 M.
