Question

Consider a general reaction czyme A(aq) = B(aq The AG of the reaction is - 7.190 kJ. mol. Calculate the equilibrium constant for the reaction at 25 °C. Kg = .00126 What is AG for the reaction at body temperature (37.0 °C) if the concentration of A is 1.7 M and the concentration of B is 0.75 M? AG = -9,3 kl. mol-
