    it is the branch of physical chemistry which deal with 1) rate of reaction (2) factor which affect rate of reaction( 3) mechanism of reaction

    2Thank You

    Pearl . 3 years, 2 months ago

    Chemical kinetics, also known as reaction kinetics, is the branch of physical chemistry that is concerned with understanding the rates of chemical reactions. It is to be contrasted with chemical thermodynamics, which deals with the direction in which a reaction occurs but in itself tells nothing about its rate.

    Ammonium chloride will have the highest solubility at 293 K temperature.
    Given,
    Temperature= 293 K.
    To find:
    The salt with the highest solubility.
    Solution:
    Let us take the following salts and assume we are mixing them in 100g of water at 293 K.

    1. Potassium Nitrate.

    2. Sodium Chloride.

    3. Potassium Chloride.

    4. Ammonium Chloride.

    The solubility of the above-mentioned salts is as follows:

    1. Potassium Nitrate = 32

    2. Sodium Chloride = 36

    3. Potassium Chloride = 35

    4. Ammonium Chloride = 37

    As we can see Ammonium Chloride has the highest solubility (37), hence it will dissolve the most in 100 g of water.

    Osmosis can be defined as the movement of solvent molecules in a solution from a region of it's higher concentration to a region of it's lower concentration across a semipermeable membrane. It depends mainly on 3 factors :- (i) The concentration of the solution. (ii) Temperature at which it occurs. (iii) Degree of dissociation or association of the solute (if possible).
