Given A + 3B
2C + D
This reaction is first order with respect to reactant A and
second order with respect to reactant B. If the concentration of A
is doubled and the concentration of B is halved, the rate of the
reaction would ________ by a factor of _______.

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...
In a chemical reaction, the reactant that limits the amount of product that can be formed...
In a chemical reaction, the reactant that limits the amount of product that can be formed is called the limiting reactant (or limiting reagent). The reaction will stop when all of the limiting reactant is consumed. In the sandwich example, bread was our limiting reactant. The reactant or reactants in a chemical reaction that remain when a reaction stops when the limiting reactant is completely consumed are called the excess reactant(s). The excess reactant(s) remain because there is nothing with...
