Chapter 5.3
Collisions, Elementary Steps, and the Energy Profile
Molecules in a flask collide billions of times a second, and almost every collision does nothing. A reaction happens only when two of them hit hard enough and the right way round.

By the end
- 01Write the rate law of an elementary step directly from its molecularity
- 02Explain rate with collision frequency, energy above the activation barrier, and orientation
- 03Use the Maxwell–Boltzmann curve to explain qualitatively how temperature changes rate
- 04Draw an energy profile with reactants, transition state, products, activation energy, and net energy change
