What else can I help you with?
When will a collision lead to a chemical reaction?
When the collision is hard and fast enough. Increasing the kinetic energy will increase the likelihood of hard and fast collisions, which will ultimately increase the rate of the reaction. (This is called collision theory.)
Start up energy of a chemical reaction?
The activation energy is the minimum amount of energy required to initiate a chemical reaction. It helps to break the existing bonds in reactant molecules and start the formation of new bonds in the product molecules. Lowering the activation energy can increase the reaction rate.
What describes the energy of activation?
Activation energy is the least amount of energy needed to start a chemical reaction. It is used to activate atoms or molecules in order for them to begin a chemical reaction.
Which molecules facilitate chemical reactions in the body by reducing the reaction's activation energy?
Enzymes
Molecules involved in a chemical reaction must collide to react What is this concept called?
This concept is called collision theory. It states that in order for a chemical reaction to occur, reactant molecules must collide with enough energy and proper orientation.

What is the difference between an effective collision and ineffective collision of reactant particles?
An effective collision between reactant particles results in a chemical reaction, while an ineffective collision does not lead to a reaction because the particles do not have enough energy or correct orientation to break and form bonds. In an effective collision, reactant molecules collide with sufficient energy and in the correct orientation to overcome the activation energy barrier and form product molecules.
Which molecules facilitate chemical reactions in the body by reducing the reaction's activation energy?
Enzymes
What increases the chance of a reaction when two molecules collide?
pressure
What is the minimum energy requirement for a collision with proper alignment to be successful?
The minimum energy requirement for a collision to be successful depends on the specific reaction and molecules involved. Generally, colliding particles need to surpass the activation energy barrier to initiate a successful reaction. This energy is determined by the specific chemical bonds involved and the reaction mechanism.
A collision may have energy in excess of the activation energy reaction may not occur?
"Collisions may have enough energy to react yet not react if the orientation of the molecules is incorrect. Difficult to explain here without graphics, but basically of the molecules are facing the wrong way it won't happen."

This concept is called collision theory. It states that in order for a chemical reaction to occur, reactant molecules must collide with enough energy and proper orientation.
Is activation energy added or just there?
Activation energy is the amount of energy that should be gained by potential reactants, for a reaction to occur. A reaction can be occurred by reducing the activation energy of the reaction or increasing the activation energy of the reactants. Activation energy should be added.
What are the molecules that bump into one another cause energy called what?
The molecules that bump into one another and cause energy are called reactants. When reactant molecules collide with enough energy, they can undergo a chemical reaction and transform into products. This collision energy is known as activation energy.
What factors the collision theory?
The collision theory states that for a chemical reaction to occur, reactant molecules must collide with sufficient energy and proper orientation. Factors that can influence reaction rates according to this theory include temperature (increased temperature increases the kinetic energy of molecules), concentration of reactants (higher concentrations lead to more collisions), and the presence of a catalyst (which can lower the activation energy required for the reaction).
