If the concentration of a such a substrate is changed from .. by what factor does the rateof the reaction..?

Question

When a substrate that is catalyzed by an enzyme is present in high concentrations, the effect on the rate of a reaction by changeing the substrate concentration can be described using zeroth-order kinetics. If the concentration of a such a substrate is changed from 2.25 × 10−3 M to 4.12 × 10−1 M, by what factor does the rate of the reaction change ?



That is rate (4.12e-1M) = f × rate (2.25e-3M)

what is the vaule of f ?

Answer 1

1 because it is zeroth-order which the rates stay the same

Answer 2

Rate is directly proportional.
