Unit 5: Kinetics

________, k, is based on the activation energy for a reaction and the temperature.

________ states reactions only occur when chemicals collide with each other with sufficient energy (activation energy)

log[A]=-kt+ln[A]₀

Rate=k

1/[A] = kt+ 1/[A]₀

A substance added to a reaction to speed it up

A substance created in one elementary step and used up in another

How long it takes for half of a substance to decompose/be consumed

t= .693/k

Not all parts of a mixture are equal, unevenly mixed

All parts of a mixture are equal, evenly mixed
