An equilibrium in which every reactant and product is in the same phase is described as:
AInstantaneous
BHomogeneous
CHeterogeneous
DDiscontinuous
Answer & Solution
Correct answer: B. Homogeneous
1. Equilibria are sorted by whether the species share a phase.
2. A homogeneous equilibrium is one in which all reactants and products are present in the same phase.
3. Any catalysts present are counted in that requirement too.
4. A heterogeneous equilibrium spans more than one phase.
