Factors affecting the reaction rate: - Concentrations of the reactants
- Temperature
- Pressure
- Stirring
- Catalysts
- Granulometry (and the surface area) of the reactants
- Reaction order
- Type of the reaction
- The solvent used
- External factors as irradiation
etc.

This is the rate at which a substance undergoes a chemical change?
This is called reaction rate.
The role of a catalyst?
A catalyst is a substance which alters the rate of a chemical reaction but is chemically unchanged at the end of the reaction. basically it increases or decreases the speed of a chemical or biological reaction, but it does not get itself involved in the reaction. hoped this helped (:
How does an increase in temperatre affect chemical reaction?
Increases reaction rate.
Substance that increases rate of chemical reactions?
catalyst
What happens If you decrease rate of chemical reaction?
The time the reaction takes increases.
Is a substance that increases the rate of a chemical reaction?
It is a catalyst.
What is a chemical that increases the rate of reaction with out being part of the compounds being formed?
This substance is called catalyst.

What is a catylast?
a substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change. a person or thing that precipitates an event.
Do enzymes speed up a chemical reactions?
Ensymes speed up a chemical reaction by acting as organic catalyst, a substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change.

enzyme
How does concentration affect the rate of a chemical reaction?
Increasing the concentration of the reactants increases the rate of the reaction.
What happens If you decrease rate of chemical reaction?
The time the reaction takes increases.
What is a substance that accelerates the rate of a chemical reaction?
a catalyst
