Given below are certain cations. Arrange them in increasing group number (Qualitative Analysis Group I to VI):A. ${\text{Al}}^{3+}$ B. ${\text{Cu}}^{2+}$ C. ${\text{Ba}}^{2+}$ D. ${\text{Co}}^{2+}$ E. ${\text{Mg}}^{2+}$

Consider the following reaction in a sealed vessel at equilibrium with concentrations: $[{\text{N}}_2]=3.0\times 10^{-3}\text{M}$, $[{\text{O}}_2]=4.2\times 10^{-3}\text{M}$, and $[\text{NO}]=2.8\times 10^{-3}\text{M}$.$2\text{NO}(g)\rightleftharpoons {\text{N}}_2(g)+{\text{O}}_2(g)$ If $0.1{\text{mol L}}^{-1}$ of $\text{NO}$ is taken in a closed vessel, what will be the degree of dissociation ($\alpha$) of $\text{NO}(g)$ at equilibrium?

The rate of a reaction quadruples when temperature changes from $27^{\circ }\text{C}$ to $57^{\circ }\text{C}$. Calculate the energy of activation. (Given $R=8.314\text{J/mol K}$)

During the preparation of Mohr’s salt solution (Ferrous ammonium sulphate), which of the following acid is added to prevent hydrolysis of ${\text{Fe}}^{2+}$?

Identify the major product C formed in the following reaction sequence:${\text{CH}}_3{\text{CH}}_2{\text{CH}}_2\text{I}\stackrel{\text{NaCN}}{\to }A\stackrel{\text{Partial Hydrolysis}}{\to }B\stackrel{{\text{NaOH, Br}}_2}{\to }C$
