What do catalyst substances do to the rate of a chemical reaction?
increase
Substances that increase the rate of a chemical reaction?
These are called catalysts.
What is the substances that increase the rate of a chemical reaction?
positive catalyst
Catalysts are that increase the rate of a chemical reaction?
element
What is the definition of catalysis?
Catalysis is the action to increase the reaction rate of a chemical reaction using substances called catalysts which are not transformed during this reaction.
What leads to an increase in the rate of a chemical reaction?
Either (or both) an increase in the reactants or temperature will increase the rate of a chemical reaction.
Which of the following tends to increase the rate of a chemical reaction?
Increasing the temperature of the reactants can increase the rate of the chemical reaction.
How does an increase in concentration affects rates of chemical reaction?
The rate of chemical reaction increase as the concentration of the chemicals increase. The reason is obvious. There is more opportunity for the atoms to come in contact with each other. This facilitates rate of chemical reaction.
An increase in temperature will cause the rate of a chemical reaction to?
Increasing the temperature the dissolving rate increase.
How does an increase in temperatre affect chemical reaction?
Increases reaction rate.
What happens to the rate constant of a chemical reaction when the temperature increases?
Increasing the temperature will cause there to be an increase in kinetic energy. This results in an increase in collision frequency, and eventually an increase in rate of reaction as well.
What causes an increase in the rate of a chemical reaction between 2 liquids?
Increasing the temperature will increase the reaction rate, as will finding a suitable catalyst.
