Which statement describes a reversible reaction at equilibrium?
(1) the activation energy of the forward reaction must equal the activation energy of the reverse reaction.
(2) the rate of the forward reaction must equal the rate of the reverse reaction.
(3) the concentration of the reactants must equal the concentration of the products.
(4) the potential energy of the reactants must equal the potential energy of the products.

Fugu, also known as puffer fish, is a sushi delicacy that can also be lethal. puffer fish contain a powerful toxin that can kill an adult a few hours after ingestion. sushi chefs who prepare fugu must be specially trained because any contamination of the toxin-free areas of the fish can be deadly. recently this toxin has been put to good use, as scientists have discovered that a purified form of it can treat severe pain in cancer patients. this recent scientific discovery would fall under which area of chemistry? applied biochemistry pure organic chemistry pure physical chemistry applied inorganic chemistry

What are the 4 phases of matter in order of increasing engery content?

How does a catalyst increase the speed of a reaction? a. the catalyst eliminates the activated complex stage, allowing products to form immediately. b. the catalyst lowers the energy level of the reactants, making it easier for them to react. c. the catalyst makes it easier for the activated complex to form, lowering the activation energy. d. the catalyst raises the energy level of the products, making the reaction finish sooner. reset next
