Question

what is hetrogenous equilibrium? two give two examples​

Answer 1

In an equilibrium the reactant and product are present in two or more than two phases it is called heterogeneous equilibrium

example

caco3(s) =cao(s)+co2(g)

Answer 2

A heterogeneous equilibrium is one in which species exist in more than one phase. Common examples include reactions involving solids and gases, or solids and liquids.

An examples of a heterogeneous equilibrium is the equilibrium established if steam is in contact with red hot carbon. In this reaction, a gas reacts with a solid:

H2O(g)+C(s)⇌H2(g)+CO(g)(8)

Another heterogeneous equilibrium involves shaking copper with silver nitrate solution; this reaction involves solids and aqueous ions:

Cu(s)+2Ag+(aq)⇌Cu2+(aq)+2Ag(s)(9)
