Collision Theory (17.5) Flashcards
- Use the postulates of collision theory to explain the effects of physical state, temperature, and concentration on reaction rates. - Define the concepts of activation energy and transition state. - Use the Arrhenius equation in calculations related rate constants to temperature.
1
Q
Collision Theory
A
A theory stating that chemical reactions occur when particles collide with enough energy and the right orientation.
2
Q
Activated Complex
A
A temporary, unstable arrangement of atoms formed during a chemical reaction, also known as the transition state.
3
Q
Transition State
A
The highest-energy point during a reaction where bonds are breaking and forming.
4
Q
Arrhenius Equation
A
A formula that shows how the reaction rate depends on the temperature and activation energy.
5
Q
Frequency Factor
A
A term in the Arrhenius equation that represents how often particles collide with the correct orientation.
