Question 1 of 15

2. Which equation shows correct form of Berthelot equation?

(P + a/TV²)(V – b) = RT

(P + a/T(V + C)²) (V – b) = RT

(P + a/T(V – C)²) (V – b) = RT

(P + a/TV²) (V + b) = RT

Question 4 of 15

5. Which is not correct about the Schottky defects?

Both cations and anions are missing from their lattice sites without affecting the stoichiometry of the compound

The defect increases the electrical conductivity of the solid due to migration of the ions into the holes.

The presence of holes causes the density of the crystal to decrease

Because of presence of holes the lattice energy decreases.
