1
Q
area of chemistry that focuses on how fast a reaction can occur
A
CHEMICAL KINETICS
2
Q
rate at which the products are formed or reactants consumed
A
focuses on reaction rates
3
Q
● One of the prevailing theories at which molecules participate in reactions
● built around a central idea that molecules must collide with each other to react.
A
COLLISION THEORY
4
Q
two requirements must be satisfied for reactants to collide successfully (to rearrange to form products).
A
- The collision must involve enough energy to produce the reaction; that is, the collision energy must equal or exceed what is called the activation energy.
- The relative orientation of the reactants must allow formation of any new bonds necessary to produce products.
5
Q
Reactions become faster by
A
- Allowing more particles to reach activation energies
- Allowing more chances for succession collisions
6
Q
refers to the amount of reactants present in the reaction.
A
Concentration
7
Q
- In solid substances, only the molecules at the surface can readily participate in effective collisions
A
Surface Area
8
Q
a measure of the average kinetic energy of particles
A
Temperature
9
Q
substance that speeds up reactions without consuming itself
A
Catalyst
