What is the Van't Hoff factor in K4 [Fe(CN)6 ] and BaCl2 ?

Solution: If (x - 6) is a factor then f(6) = 0, that is  6³ + a6² + b(6) - b = 0  216 + 36a + 6b - b = 0  36a +...

Physical significance of ‘a’: ‘a’ is a measure of the magnitude of intermolecular attractive forces within a gas. Physical significance of ‘b’: ‘b’ is a measure of the volume of...

 (a) α = i - 1/n -1  (b) α = i - 1/1/n - 1

Speed of the police van, vp = 30 km/h = 8.33 m/s Muzzle speed of the bullet, vb = 150 m/s Speed of the thief’s car, vt = 192 km/h = 53.33...

(b) : Power factor = R/√(R2 + L2ω2).

(c) : van der Waals constant for volume correction b is the measure of the effective volume occupied by the gas molecules.

(a) Van’t Hoff factor: (i) May be defined as the ratio of normal molecular mass to observed molecular mass or the ratio of observed colligative property to calculated colligative property.  (ii)...

(1) Critical temperature ∝ vanderwaal constant(a) maximum "a" => gas with maximum TC => easiest liquification = NH3

Two solution of same concentration would mean that the molarity of both the solutions is equal. Therefore, first we need to calculate the molarity of NaCl solution. Mass of NaCl =...
