factors that could affect a reaction rate
a substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change.
Catalysts increase the rate of reaction without being used up. They do this by lowering the activation energy needed.
ith a catalyst, more collisions result in a reaction, so the rate of reaction increases. Different reactions need different catalysts.
Temperature
the degree or intensity of heat present in a substance or object, especially as expressed according to a comparative scale and shown by a thermometer or perceived by touch.
Increasing the temperature increases reaction rates because of the disproportionately large increase in the number of high energy collisions.
The rate of a reaction increases if: the temperature is increased. the concentration of a dissolved reactant is increased.
Surface Area
The area of such an outer part of uppermost layer.
Increasing the surface area of a substance generally increases the rate of a chemical reaction.
The rate of a chemical reaction can be raised by increasing the surface area of a solid reactant.
concentration
concentration is the abundance of a constituent divided by the total volume of a mixture.
If the concentration of a dissolved reactant is increased, or the pressure of a reacting gas is increased
Increasing the concentration of one or more reactants will often increase the rate of reaction.
The Nature of the Reactants
Chemical reactions proceed at different rates. The factors that affect reaction rates are: surface area of a solid reactant. concentration or pressure of a reactant.
Chemical reaction proceed at different rates. The factors that affect reaction rates are, surface area, concentration or pressure of a reactant
Increasing the concentration of one or more reactants will often increase the rate of reaction. This occurs because a higher concentration of a reactant will lead to more collisions of that reactant in a specific time period.
