What defines a homogeneous equilibrium?
AEvery species sits in one single phase
BEvery species has the same coefficient
CEvery species is present in equal amounts
DEvery species is a gas at the temperature
Answer & Solution
Correct answer: A. Every species sits in one single phase
1. Homogeneous means one phase throughout the mixture.
2. All reactants and products of a homogeneous equilibrium sit in that single phase.
3. The two common cases are liquid solutions and mixtures that are entirely gaseous.
4. Coefficients and amounts have nothing to do with the classification.
