Random example:
X+Y -> A+G (fast)
A -> C + D (SLOW)
C+E -> F (fast)
So the rate law equation would be rate = k [A] - first order kinetics. Now what if a question asked what changes would affect the rate of the overall reaction? According to the textbooks, the reactants of the rate determining step (RDS) largely dictate the overall rate. What about changes made to the products of the RDS?
For example, lets say I add more C and D as the reaction occurs, wouldn't that slow the reaction down as it pushes the reaction to the left? Le Chatlier principle is applied during equilibrium, but can it also be applied in this case?
Furthermore, what about the amount reactants and products in the other steps? Let's say I increase the concentration of X and Y, therefore the reaction produces more A, thereby affecting the rate of the overall reaction.
Thank you.
