### Rate of Reaction vs. Reaction Rate Constant

Can someone please explain the difference between rate of reaction and reaction rate constant?

### Re: Rate of Reaction vs. Reaction Rate Constant

The rate of reaction tells us how the rate is related to concentrations, since by definition it is a change in concentration of reactants over time, while the reaction rate constant depends on temperature and activation energy, which is why we can calculate the reaction rate constant using any concentration.

### Re: Rate of Reaction vs. Reaction Rate Constant  [ENDORSED]

The rate of the reaction is a measurement of the change in concentration of a reactant or product over a unit of time. For example, the equation to find a rate could be written as "rate = k[A]", where k is the reaction rate constant and A is a reactant. Within the rate law, the reaction rate constant "k" is considered a proportionality constant between the rate and concentrations. It's unique to a reaction depending on its temperature, and it also consists of different units depending on the order of the reaction.
