Out of the following pairs, predict with reason which pair will allow greater conduction of electricity:
(i) Silver wire at 300^oC or silver wire at 600^oC.
(ii) $0\cdot 1\mathrm{M} {\mathrm{CH}}_3\mathrm{COOH}$ solution or $1\mathrm{M} {\mathrm{CH}}_3\mathrm{COOH}$ solution.
(iii) KCl solution at 200C or KCl solution at 500C.

(a) (i) Silver wire at will allow greater conduction of electricity because as temperature decreases, resistance decreases. Hence, conduction increases.

(ii) 0.1 M CH₃COOH will allow greater conduction of electricity, because on dilution degree of ionization increases hence conduction increases.

(iii) KCl solution at will allow greater conduction of electricity, because at high temperature mobility of ions increases and hence conductance increases.
