What are the different factors affecting the rate of chemical
reactions
Temperature the degree or intensity of heat
present in a substance or object, especially as
expressed according to a comparative scale
and shown by a thermometer or perceived by
touch.
Concentration the measurement of the
number of particles present in a given volume,
often in a mixture or solution
Surface area The area occupied by a threedimensional object by its outer surface
Catalyst a substance that increases the rate
of a chemical reaction without
itself undergoing any permanent chemical
change.
Temperature
If the
temperature is
higher the rate
of reaction will be
quicker
Concentration
• If the reactants in a chemical reaction is diluted the time
taken will be slower than if it wasn’t diluted
SURFACE AREA
the amount of surface that a material has per
unit mass
Surface area
CATALYST
• a substance that increases the rate of a chemical reaction without itself undergoing any
permanent chemical change.
