High school5/5 lessons
Thermochemistry and kinetics
Energy exchanged by a reaction, its rate, orders, and catalysis. When and how a reaction proceeds.
- 01
Chemical reaction energy
Exothermic/endothermic reactions, bond energy, application to combustion and batteries.
10 min - 02
Reaction enthalpy
Defining ΔH, Hess's law, calorimetry. First contact with the first law of thermodynamics.
11 min - 03
Reaction rate
Defining v = −dC/dt (reactant) or +dC/dt (product). Kinetic monitoring: conductivity, spectrophotometry.
11 min - 04
Rate laws and reaction orders
Order 0, 1, 2 — differential and integrated equations, half-life. Experimental determination.
12 min - 05
Catalysis
Catalyst, activation energy, energy profile. Homogeneous, heterogeneous, enzymatic catalysis.
