What happens when a catalyst is used in a chemical reaction? the reaction rate increases. the reaction rate decreases. the reaction rate does not change. the reaction process decreases.

Which element would mostly likely have an electron affinity measuring closest to zero

The activation energy for this reaction is 75 kj·mol–1. the enzyme catalase (found in blood) lowers the activation energy to 8.0 kj·mol–1. at what temperature would the non-catalyzed reaction need to be run to have a rate equal to that of the enzyme-catalyzed reaction at 25°c?

Astable atom that has a large nucleus most likely contains 1. more neutrons than protons. 2.more protons than neutrons. 3.equal numbers of protons and neutrons. 4.changing numbers of protons and neutrons.
