CATALYSTS
DEFINITION:
A catalyst is a substance that increases the rate of a chemical reaction
without being consumed by the overall reaction and used up in the
process.
KEY POINTS:
· A catalyst may react to form an intermediate. The catalyst is later
regenerated, so the catalyst does not undergo any permanent change.
· The presence of a catalyst allows a reaction to proceed via a
different/alternative route with a lower activation energy, giving rise to an
increased reaction rate.…read more

Here's a taster:

Many industrial processes rely on catalysis to
reduce costs as catalyst development and improvement often leads to
greater profitability with products being produced more quickly and easily.
· It is estimated that approx. 80% of industrial processes involve catalysts
and about half of the periodic table of elements are either catalysts or can
be found in compounds that are used in catalysts.…read more
