Write the equilibrium constant expressions for the following equilibria.

4. CCl4(g) + HF(g) ⇌ CFCl2(g) + HCl(g)
5. NH4Cl(s) ⇌ NH3(g) + HCl(g)
6. SO3(g) + H2O(1) ⇌ H2SO4(1)

1. K = [CF2Cl2] [HCl]^2 / [CCl4] [HF]^2

2. K = [NH3] [HCl] / [NH4Cl]

3. K = [H2SO4] / [SO3] [H2O]

Explanation:

The equilibrium constant for a chemical reaction is simply the ratio of the concentration of the products to that of the reactants

The equilibrium constant for the reactions are written below.

1. CCl4(g) + 2HF(g) ⇌ CF2Cl2(g) + 2HCl(g)

K = [CF2Cl2] [HCl]^2 / [CCl4] [HF]^2

2. NH4Cl(s) ⇌ NH3(g) + HCl(g)

K = [NH3] [HCl] / [NH4Cl]

3. SO3(g) + H2O(1) ⇌ H2SO4(1)

K = [H2SO4] / [SO3] [H2O]

it is to be noted that an alpha particle is an helium nucleus. so it contains 2 protons 2 neutrons and has a mass number of 4. when alpha decay particles are ejected from the nucleus it gets transformed into an atom which has atomic number less than 2 and a mass number less than 4.

an equation that could represent alpha decay is radium 226 decay of alpha particle forms radon 222.
