Heat increases the rate of reaction as heat makes particles vibrate and increases the frequency of collisions between particles. This means that more particles can react in a shorter amount of time.
A catalyst also increases the rate of reaction as it provides extra surface area for the reactions to happen on and in some cases, attacks certain bonds to initiate the reaction.
If you wanted to decrease the rate of reaction, cooling the vessel would do the trick.
What else can I help you with?
This is the rate at which a substance undergoes a chemical change?
This is called reaction rate.
What do enzymes change about a chemical reaction?
The Reaction Rate
What parameter involved in a chemical reaction will change with the addition of a catalyst?
The rate of a chemical reaction will change in the presence of a catalyst, unless the reaction is already at equilibrium.
When is reaction in chemical equilibruim?
a reaction is in chemical equilibrium when the rate of evaporation is equal to the rate of condensation. molecules are leaving and returning to the container at the same rate. Equilibrium can only be reached in a close container.
Is milk souring an example of chemical change?
Yes it is a chemical reaction between the calcium and the oxygen [i may be wrong their] but the rate of reaction is very slow.
This is the rate at which a substance undergoes a chemical change?
This is called reaction rate.
How does temperature affect physical and chemical chemical change?
A change in temperature can change the rate of physical or chemical change.
Does the rate constant change with concentration in a chemical reaction?
Yes, the rate constant can change with concentration in a chemical reaction.
How does catalyst effect chemical change?
A catalyst alters the rate of a chemical reaction.
What do enzymes change about a chemical reaction?
The Reaction Rate
What is a Substance that speeds up rate of a chemical change?
A catalyst.
How do chemical reactions change the rate?
By changingthe temperaturethe pressurepresence the catalysts
How catalyst can change the rate of a chemical reaction?
speeds it up or starts it
How is the reaction rate measured in chemical reactions?
The reaction rate in chemical reactions is measured by monitoring the change in concentration of reactants or products over time. This can be done by measuring factors such as the amount of gas produced, color change, or temperature change. The rate of reaction is typically expressed as the change in concentration per unit time.
What things may change the rate of chemical reactions in a cell?
temperature and pH
How can you change the rate of chemical change in a substance?
This is a very vague question and would depend on the chemical that you are talking about. The easiest way I can think to explain it on a wide variety of chemicals is by using a catalyst (speeds up the process of a chemical reaction), or the use of an antagonist (Slows a chemical reaction). I hope this helps, but without any specific chemicals being named this is the best i can do. :) By heating we can change the rate of chemical change(reaction).
Which organ speeds up the rate of chemical change?
There are five organs in our body that secrete digestive juices, which contain enzymes to speed up the rate of chemical change. These are the mouth, stomach, pancreas, liver and gall bladder.
