$500 Question from C4



Description of how concentration and

temperature are related to the rate of a

chemical reaction. Then identify and

describe one more factor that can affect

reaction rate.

$500 Answer from C4

What is: Concentration describes the number of particles

in a given volume. As the concentration of the reactants

increases, there are more particles to collide and react with

one another. This can increase the reaction rate.

Temperature is related to the rate of a reaction.

Temperature is also related to energy, when you add energy

to a reaction, it increases particle motion. This increase in

motion is measured by an increase in temperature. Reactions

at higher temperatures have reactant particles that are moving

faster. This results in more reactant collisions and a faster

reaction rate. Increased surface area means that more of the

surface of the reactant is exposed. As surface area increases,

the rate of reaction increases.
