How Does Temperature Affect the Rate of Reaction? | Sciencing

The effect of temperature on rate of reaction is just one of the things that can affect how a reaction proceeds, that is, how quickly whatever reactants are present become transformed into products. Of course, many of these factors are active at all times and can have competing influences on the overall rate of a given reaction.
