Upper N upper H subscript 4 upper C l (s) right and left arrows stacked above each other upper N upper H subscript 3 (g) plus upper H upper C l (g)

Explanation:

The given equation is;

  NH₄Cl    ⇄      NH₃   +    HCl

This equation is clearly different from the other ones.

  • In the reactant going forward, there is a right and left arrows stacked above each other.
  • The symbol is  ⇄  and it is used to show reversibility of chemical reactions.

Consider the reaction CaCO3(s) --> CaO(s) + CO2(g)
tankabanditka [31]

Answer:

Kc = [CO2], that is to say it is equal to the concentration of CO2

Explanation:

It is a heterogeneous equilibrium since the substances that participate in the reaction are in different phases

In the heterogeneous limestone decomposition reaction:

CaCO3(s) --> CaO(s) + CO2(g)

The equilibrium constants are:

Kc = [CO2(g)]; Kp = PCO2(g); Kc = Kp (R T)^ −(1−0) = Kp (R T)^ −1

The equilibrium situation is not affected by the amount of  solid or liquid, as long as these substances are present.

The equilibrium constant is independent of the  amounts of solids and liquids in equilibrium.
