Rate of Reaction

Rates of Chemical Reactions

The rate of a chemical reaction tells us how quickly reactants are converted into products. In industry, reaction rates are very important. However, faster reaction rates may not always be better.

Maximum profit

In industry, making the required amount of product as cheaply as possible maximises all-important profit.

Faster reactions

Faster reactions are often better as they yield more product in a given amount of time.

Drawbacks

It may be expensive to generate the conditions for very fast reactions.
There can be safety concerns associated with very fast reactions.
- Therefore, reaction rates used in industry are the result of a trade-off between speed, cost and safety.
