With examples in each, differentiate between homogeneous and heterogeneous equilibrium
Accepted Answer
Homogeneous Equilibrium:
A homogeneous equilibrium involves reactants and products that are in the same phase, usually a single phase such as a gas or a liquid.
*Example: The dissociation of hydrogen iodide (HI) gas:
2HI(g) H2(g) + I2(g)
Heterogeneous Equilibrium:
A heterogeneous equilibrium involves reactants and products that are in different phases, such as a solid, liquid, or gas phase.
*Example: The dissolution of calcium carbonate (CaCO3) in water:
CaCO3(s) Ca2+(aq) + CO32-(aq)
