The dispersed phase and dispersion medium in smoke, respectively, are:
Smoke is a colloidal system in which solid particles (such as carbon and other particulates) are dispersed in a gaseous medium (air).
- Dispersed Phase: Solid particles
- Dispersion Medium: Gas (air) Such systems are categorized as aerosols, which include both smokes (solid in gas) and fogs (liquid in gas).
A solid is dissolved in 1 L water. The enthalpy of its solution (\(\Delta H_{{sol}}^\circ\)) is 'x' kJ/mol. The hydration enthalpy (\(\Delta H_{{hyd}}^\circ\)) for the same reaction is 'y' kJ/mol. What is lattice enthalpy (\(\Delta H_{{lattice}}^\circ\)) of the solid in kJ/mol?
Arrange the following in increasing order of their pK\(_b\) values.
At $ T $ (K), the following data was obtained for the reaction: $ S_2O_8^{2-} + 3 I^- \rightarrow 2 SO_4^{2-} + I_3^- $.
From the data, the rate constant of the reaction (in $ M^{-1} s^{-1} $) is:
