The incorrect statement is option (n)
Physisorption is an exothermic process. Hence increases in temperature decreases the Physisorption

In general, specific conductance of an electrolyte decreases with dilution.So,0.002N solution has least specific conductance.

IF = 96500 C = charge of one mole of e^- charge of 6.022 x 10^-23 electron

Nylon - 2 - Nylon - 6
 It is a co - polymer which contains polyamide linkages. It is obtained by the condensation polymerisation of the monomers, glycine and E-amino caproic acid.

Glucose reacts with HCN to form cyanohydrin.

(i) Gold number' is a measure of protecting power of a colloid.
(ii) Gold number is defined as the number of milligrams of hydrophilic colloid that will just prevent the precipitation of 10ml of gold solon the addition of 1ml of 10% NaCl solution.
(iii) Smaller the gold number greater the protective power.

E = E^O- 2.303 \(\frac { RT }{ 2F } \) log Zn²⁺
E_Zn²⁺/Zn = E_{Zn²⁺/ Zn}- 2.303 \(\frac { RT }{ 2F } \)  log [Zn²⁺]
