2. When using the method of initial rates to determine the reaction order of each individual reactant, why must data only be used in which one reactant is changing concentration but not the other reactants? 3. Briefly explain why the number of total drops being mixed in each experiment is kept constant throughout all five experiments. 4. Sketch a molecular‐level picture that illustrates why reaction rate increases when the concentration of a reactant is increased. Note – this might be...

Isolation Method of Rate Law Determination
Consider the base hydrolysis of an ester RCOOR' + OH-→ RCOO-+ R'OH (where R and R"represent organic groups) The kinetics of this reaction, for a particular ester, were studied using the isolation method When [OH>> [RCOOR'] a pseudo-rate law can be posed: With initial concentrations: [OH-]0 = 0.800 M [RCOOR']0 = 0.0010 M, a plot of In[RCOORT versus t gave a straight line with slope =-1.01 s-1 and y-intercept =-6.91 What is the order...

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...
