Low rate constant
WebAnh Hoang Le. As everyone knows: Vmax = Kcat x [E]t. Vmax unit eg umol.min-1 (Im sorry, I mistyped this before) Kcat unit should be min-1 or s-1. So my question is, if the [E]t is really a ... Web2 jan. 2024 · The constant k () is seen to be the rate constant in a solution of zero ionic strength, that is, at infinite dilution. Equation (NN) also predicts that reactions between ions of the same sign should speed up as the ionic strength increases, whereas reactions between oppositely charged ions should slow down with increasing ionic strength.
