Most of the time, the rate of a reaction depends on the
concentration of the reactant. In the case of second-order
reactions, the rate is proportional to the square of the
concentration of the reactant.
Select the image to explore the simulation, which will help you
to understand how second-order reactions are identified by the
nature of their plots. You can also observe the rate law for
different reactions.
In the simulation, you can select one of the three different...

Make appropriate plots or perform linear regression using these data to test them for fitting zero-, first-, and second-order rate laws. Test all three even if you happen to guess the correct rate law on the lint trial. Determine the rate constant for the reaction. Using the rate law that you have determined, calculate the half-life for the reaction. At what time will the concentration of A be 0.380?

A student measures the reaction H2(g) + Cl2(g) <=> 2 HCl(g) concentrations at a few different temperatures and obtains the equilibrium constant. The student wants to use the van't Hoff equation to roughly determine the reaction enthalpy assuming that it does not change over the region of interest. T(K) 300 500 1000 Keq 4x1031 4x108 So the student plots the data in the Ink vs 1/T diagram and obtains a linear fitting shown below: 80 4x1018 60 In(K) 40 20...
