A very small amount of catalyst alters the rate of a reaction

Ni is used as catalyst in the manufacture of ammonia.

None of these

Raoult’s law states that the vapour pressure of a component over a solution is proportional to its mole fraction

The osmotic pressure `(pi)` of a solution is given by the equation `pi` = MRT where M is the molarity of the solution

The correct order of osmotic pressure for 0.01 M aqueous solution of each compound is `BaCl_2 gt KCl gtCH_3COOH gt` sucrose.

Two sucrose solutions of same molality prepared in different solvents will have the same freezing point depression.

Raoult’s law states that the vapour pressure of a component over a binary solution of volatile liquids is directly proportional to its mole fraction

Two sucrose solutions of the same molality prepared in different solvents will have the same depression in freezing point

The correct order of osmotic pressures of 0.01 M solution of each compound is `BaCl_(2) gt KCl gt CH_(3)COOH gt` "glucose"`

In the equation osmotic pressure `pi` = MRT, M is the molarity of the equation
