MediumWhat is heterogeneous equilibrium? Give its types with examples.
Equilibrium in a system having more than one phase is called heterogeneous equilibrium.
Type-$1$: Liquid $\rightleftharpoons$ Gas
Example: $H_2O_{(l)} \rightleftharpoons H_2O_{(g)}$
Type-$2$: Solid $\rightleftharpoons$ Aqueous solution
Example: $Ca(OH)_{2(s)} \rightleftharpoons Ca^{2+}_{(aq)} + 2OH^-_{(aq)}$
Example: $C_{12}H_{22}O_{11(s)} \rightleftharpoons C_{12}H_{22}O_{11(aq)}$
Type-$3$: Solid $\rightleftharpoons$ Gas
Example: $CaCO_{3(s)} \rightleftharpoons CaO_{(s)} + CO_{2(g)}$
Example: $NH_4Cl_{(s)} \rightleftharpoons NH_{3(g)} + HCl_{(g)}$
Example: $C_{(s)} + CO_{2(g)} \rightleftharpoons 2CO_{(g)}$

View SolutionOne mole each of $He$ and $A(g)$ are taken in a $10 \text{ L}$ closed flask and heated to $400 \text{ K}$ to establish the following equilibrium: $A(g) \rightleftharpoons B(g)$. $K_{c}$ for this reaction at $400 \text{ K}$ is $4.0$. The partial pressures (in $\text{atm}$) of $He$ and $B(g)$ are respectively (at equilibrium) (Assume $He$,$A(g)$ and $B(g)$ behave as ideal gases) (Given: $R = 0.082 \text{ L atm K}^{-1} \text{ mol}^{-1}$)
