Temperature plays in important part in most chemical reactions. Generally speaking,
the higher the temperature, the higher the rate of reaction due to the increased
amount of energy available as well as an increase in particle contact.
Suppose a chemical reaction was discovered in which temperature was not relevant
at all. An experiment was devised where all other factors were allowed to vary -
pressure, number of particles, etc. - and the temperature was increased from 10°C to
50°C while the rate of the reaction was measured.
