Standard chemical kinetics tool for constant-rate surface and enzyme-saturated reactions.

Calculation Methodology

Zero-Order Integrated Rate Law: [A]t = [A]0 - k * t (for [A]t >= 0). Half-Life: t_1/2 = [A]0 / (2 * k). Complete Consumption Time: t_comp = [A]0 / k. Rate constant k has units of M/s.

Frequently Asked Questions

Because the rate-limiting step occurs on saturated surface catalytic sites or saturated enzymes; adding more reactant cannot increase speed when all catalytic active sites are already 100% occupied.
