===Meaning===
'''Rate of reaction''' is a measure of how quickly a the [[reactant]]s [[Chemical Reaction|reactionreact]] to create the [[product]] can happens.
===About the Rate of Reaction===
: The longer the [[time]] taken for a [[Chemical Reaction|reaction]] the lower the '''rate of reaction'''. The shorter the [[time]] taken for a [[Chemical Reaction|reaction]] the higher the '''rate of reaction'''.
: High '''rates of reaction''' are important to in industries where a lot of [[product]]s are needed in a short amount of time. This can save money.
: Low '''rates of reaction''' are important in [[material]]s that [[Corrosion|corrode]] with [[chemical]]s in the environment. This allows them to last a long time before destroyed by [[Oxidation]] or [[Chemical Weathering|chemical weathering]].

===Determining the Rate of Reaction===
There are two approaches to finding the '''rate of reaction''' for some [[chemicals]].
*Find out how quickly the [[reactant]]s are used up.
*Find out how quickly new [[product]]s are made.

====Continuously Measuring the Mass====
