IB Chemistry HL 2.3.1 Dynamic equilibrium
Focus on what examiners look for at equilibrium: both reactions still occur, the forward and reverse rates become equal, and observations must be constant.
How this is tested
- state dynamic equilibrium means reactants and products still react; the position is not shifting
- sketch rate vs time curves where forward starts higher, then both meet at the same constant rate
- judge colorimetry evidence by waiting until absorbance, color, or [NO2] becomes constant
