What is the likely keq for an enzyme that has a deltaG =-18.3kj/mol?

One liter of a 0.1 M Tris buffer (pKa of Tris = 8.3, see Table 2.4) is prepared and adjusted to a pH of 2.0. A) What are the concentrations of the conjugate base and weak acid at this pH?Answer with 2 significant digits. I have solved for [HA] = 0.10 Can you please help solve for [A-] = ?

Given that the AG" values for the hydrolysis of glucose 1-phosphate and glucose 6-phosphate are approximately -21 kJ/mol and –14 kJ/mol, respectively, which statement is true regarding the isomerization shown? glucose 1-phosphate → glucose 6-phosphate O The reaction can likely proceed in either direction and will therefore depend on the concentrations of glucose 1-phosphate and glucose 6-phosphate. O Only the anabolic direction will occur because the free energy change is positive. O The reaction will proceed in both directions simultaneously. This reaction can only proceed in one direction and must be the rate limiting reaction for this point in metabolism.

If a data from an enzyme experiment is plotted as a Lineweaver - Burk plot, and the Vmax is 0.02 sec/mol, and x-intercept is -2.5 mM-1, then what is the KM value?
