AIons, energies and concentrations at the end
BIncrease, constant and equilibrium quantities
CInput, catalyst and expected final quantities
DInitial amounts, changes and final amounts
Answer & Solution
Correct answer: D. Initial amounts, changes and final amounts
1. The first row lists the initial concentrations, taken before any reaction has occurred.
2. The second row lists the changes that occur as the mixture moves toward equilibrium.
3. The third row lists the concentrations once equilibrium has been reached.
4. The letters therefore stand for Initial, Change and Equilibrium.
