【用途】 With this web page you can simulate the kinetics of reaction mechanisms. The idea is to

write a mechanism and from that

follow the course of concentrations or rates of change in concentration of reactants, catalysts, intermediates, and products over time. In addition,

graph many different relationships related to the reaction either for one species or for the whole set, including:
[X], ln[X], 1/[X], or d[X]/dt vs. time, and
d[X]/dt vs. time, [X], or [X]^2
