Answer: the speed at which products form
Explanation:
Rate of a reaction is defined as the speed at which a chemical reaction proceeds. It is often expressed in terms of the concentration of a reactant that is consumed in a unit time or the concentration of a product that is formed in a unit of time.
For a general reaction :![A\rightarrow B](https://tex.z-dn.net/?f=A%5Crightarrow%20B)
![Rate=-\frac{d[A]}{dt}](https://tex.z-dn.net/?f=Rate%3D-%5Cfrac%7Bd%5BA%5D%7D%7Bdt%7D)
or ![Rate=+\frac{d[B]}{dt}](https://tex.z-dn.net/?f=Rate%3D%2B%5Cfrac%7Bd%5BB%5D%7D%7Bdt%7D)
where d[A] = change in concentration of reactant A
d[B] = change in concentration of product B
dt = time interval
