Factors affecting rate of reactions

what is the rate of reactions?

How fast one or more substances can change into new substances

surface area

as surface area increases the rate of reactions increases (can occur by crushing, breaking, or grinding something)

Temprature

As temperature increases the rate of reactions increases. If temperatures decreases the rate of reactions decreases

Concentration

A measurement of how much solute exists within a certain volume of solvent

- as concentration increases the rate of reactions increases

catalyst

- substance that speeds up the rate of reaction

- they are present with the reactants however they do not get consumed during the reaction

Enzyme (catalyst)

salary glands release enzyme (a catalyst) to help break down food

presence of an Inhibitor

Inhibitors slow down chemical reactions (decrease the rate of reaction)

- galvanization is an example of this
