Question

What happens to a reaction's rate when there are increasing amounts of reactant added?

Question 2 options:

Chemical reaction rates continue to increase linearly, but enzyme catalyzed reactions will reach a maximum rate.

Both chemical reaction rates and enzyme catalyzed reaction rates will continue to increase linearly.

Enzyme catalyzed reaction rates continue to increase linearly, but chemical reactions will reach a maximum rate.

Both chemical reaction rates and enzyme catalyzed reaction rates will reach a maximum rate.

Enzyme catalyzed reaction rates continue to increase linearly, but chemical reactions will reach a maximum rate.

Both chemical reaction rates and enzyme catalyzed reaction rates will reach a maximum rate.

The rate of reaction -r= K[Concentration]n, n is the order of reaction

with increasing concentration for reactions n>0, with increased concentration, the rate constant increases

For Enzyme based reaction, the rate V= Vmax[S]/(KM+S)

With increased substrate concentrations S> KM and V=Vmax and hence the rate reaches maximum ( A is the correct answer)
