Chemical Reactions Flashcards
What is a chemical reaction?
Chemical reactions are the processes by which chemicals interact to form new chemicals with different compositions.
What is activation energy?
Activation energy is the minimum energy required to cause a process (such as a chemical reaction) to occur.
How does a chemical reaction take place in terms of particles collisions and energy?
The collision theory of chemical reactions is based upon the idea that for reactions to occur the particles, whether atoms, ions or molecules, must collide for a reaction to occur.
What is an exothermic reaction?
An exothermic reaction is a reaction in which energy is released in the form of light or heat.
What is an endothermic reaction?
An endothermic reaction is any chemical reaction that absorbs heat from its environment.
