By Dr. Doug Stewart<\/div>\n

The reaction rate<\/strong> tells us how quickly reactants → products<\/span>.<\/p>\n

\nDid you know?\n<\/div>\n

\nExplosions are the result of very high chemical reaction rates. Explosives are solid chemicals that react very quickly to produce a hot gas, which blows everything outwards.\n<\/div>\n

\nchemical reactions<\/div>\n<\/div>\n

Not all chemical reactions<\/a> are created equal. <\/p>\n

Some are naturally fast, such as when you put a flame to hydrogen in the presence of oxygen in the pop test.<\/p>\n

Some are naturally slow, such as iron rusting in the presence of oxygen and water.<\/p>\n

Things that affect chemical reaction rates<\/h2>\n

It’s possible to speed up or slow down the rate of a reaction by changing one or more of three things: <\/p>\n

    \n
  • temperature<\/strong> <\/li>\n
  • particle size<\/strong><\/li>\n
  • concentration of reactants<\/strong><\/li>\n<\/ul>\n

    You can also speed up a reaction using something called a catalyst<\/strong>, which we’ll look at later on this page. <\/p>\n

    Examples of changing reaction speeds<\/h2>\n
