The rate of reaction (reaction rate) is the
time it takes for a chemical reaction to
occur. the reaction rate is controlled by
many factors, including the
concentration of the reactants, the
temperature, the surface area, pressure,
and the presence of the catalyst.
many people are familiar with the rate of
reaction as a result of using sugar to
sweeten either hot or cold tea. sugar
dissolves faster in a warm liquid than in
a cold liquid – this is an example of how
temperature influences the reaction rate
