Catalysts

A catalyst is a substance that WHAT of a chemical reaction without WHAT by the reaction (their WHAT)

A catalyst is a substance that INCREASES the RATE of a chemical reaction without BEING CONSUMED by the reaction (their REGENERATIVE)

Catalysts provide WHAT for chemical reactions

Alternate pathways

They WHAT the WHAT required for a reaction to take place which results in the production of a WHAT of products in a given length of time (even at lower temperatures)

They LOWER the ACTIVATION ENERGY required for a reaction to take place which results in the production of a GREATER YIELD of products in a given length of time (even at lower temperatures)

Catalysts are often used in industry to WHAT the reactions and obtain a reasonable WHAT under reasonable conditions

Catalysts are often used in industry to SPEED UP the reactions and obtain a reasonable REACTION RATE under reasonable conditions

In cars, we have WHAT that use Pt(s), Pd(s) and Rh(s) to speed up the combustion of exhaust gases so that more of the products are WHAT (WHAT instead of NOx, WHAT instead of CO)

In cars, we have CATALYTIC CONVERTERS that use Pt(s), Pd(s) and Rh(s) to speed up the combustion of exhaust gases so that more of the products are HARMLESS (N2 instead of NOx, )2 instead of CO)

The oil and gas industry uses catalysts in the WHAT of WHAT and WHAT to make more marketable fuels like gasoline

The oil and gas industry uses catalysts in the CRACKING and REFORMING of CRUDE OIL and BITUMEN to make more marketable fuels like gasoline
