Which of the following are correct statements?

Engineering

Chemistry

Colloids Preparation and Properties

Question

Ester hydrolysis is slow in beginning and becomes faster after some time due to auto catalysis.

Viscosity of oil in water type emulsion is greater than viscosity of water in oil type emulsion.

for two real gases A and B, P vs V graph at a particular temperature T is shown, extent of adsorption for gas B > A.

If a colloidal shows movement towards cathode during electrophoresis then the same colloid will show movement towards anode in electroosmosis.

(A)    During ester hydrolysis an acid is formed as product so (H⁺) increases and rate also increases.
(B)   From graph critical temperature of B > A so extent of adsorption of B will be more
(C)   Correct because in colloids dispersed phase and dispersion medium have opposite chargers.
(D)   As fraction of oil increases viscosity increases.
