How does a catalyst change the rate of a chemical reaction?
Lowers the activation energy of a reaction, therefore speeding the reaction up.Catalysts speed up chemical reactions. They do not change the products or reactants of the reaction, and are not used up or consumed in the reaction. Biological catalysts are called enzymes. Catalysts lower the activation energy (or energy needed to start a reaction), and cause the reaction to occur more quickly.
What is the drug injected into the heart to protect from chemical agents?
There are two drugs you get to carry around with you to keep you from dying in a chemical agent attack. One's atropine--one of the things nerve gas does to you is slows down your heart, and atropine speeds it up. The other is "2 Pam Chloride" which neutralizes the nerve agent.
How do you change the shutter speed on a Samsung S630?

What happens to the heart rate when one is startled?

Substance that speeds up a chemical reaction without undergoing a permanent change -?
Catalyst
Name for any substance that speeds up the rate of chemical reaction?
A substance that speeds up a chemical reaction is known as a CATALYST.
A substance that speeds up a chemical reaction without undergoing a permanent change itself is?
A substance that speeds up a chemical reaction without undergoing a permanent change itself is called a catalyst. Catalysts work by providing an alternative pathway for the reaction to occur, thereby lowering the activation energy needed for the reaction to proceed. Once the reaction is complete, the catalyst remains unchanged and available to facilitate more reactions.
Substance that speeds up a chemical reaction?

What c word defines substance that speeds a chemical reaction without being consumed?
Catalyst is the substance that speeds up a chemical reaction without being consumed in the process.
What is a substance that speeds up a chemical reaction but is not a reactant product?
An enzime.
What is substance that speeds up the rate of a chemical reaction is called a(an)?
a catalyst
What is a substance that speeds up a chemical process?
catalyst-by lowering activation energy
What is a substance which helps make a chemical change happen but is not changed itself in the process is called?
Catalyst: a substance which speeds up a chemical change or enables the change to take place at a lower tempature, and is not changed or used up in the reaction.
What is a substance that speeds a chemical reaction without itself being charged?
A catalyst
