chemical reaction
the process by which one or more substances change to produce one or more different substances
product
a substance that forms in a chemical reaction
Reactant
a substance that takes part in and undergoes change during a reaction.
Enzyme
A type of protein that speeds up a chemical reaction in a living thing
catalyst
substance that speeds up the rate of a chemical reaction
How does surface area affect the rate of reaction?
The more surface area, the faster the reaction, because there's more room available for colisions
How does temperature affect enzyme activity?
increases chance of enzyme substrate collisions so enzyme activity increases as temperature increases up to an optimal temperature.
How does concentration affect the rate of reaction?
It increase the rate of reaction up to an optimal concentration.
