If the rate-determining step limits the speed of a reaction, which statement is correct? Even if one or more fast steps occur in a reaction, the overall reaction cannot proceed any faster than the slowest step.
If the first step is slow and the second step is fast, then the second step should determine the rate of the overall reaction.
Increasing the concentration of a molecule that occurs in a fast step after a slow step will increase the overall rate of the reaction.
In a unimolecular reaction where A decomposes to B and C, the rate of the reaction will decrease if the concentration of A is increased.
