The oxidation of ${\mathrm{SO}}_2$ by ${\mathrm{O}}_2$ to ${\mathrm{SO}}_3,$ is an exothermic reaction. The yield of ${\mathrm{SO}}_3$ will be maximum if

For the reaction $2\mathrm{A}+\mathrm{B}\rightleftharpoons \mathrm{C}, \mathrm{\Delta H}=\mathrm{x} \mathrm{cal},$ which one of the following conditions would favour the yield of $\mathrm{C}$ on the basis of the Le-Chatelier's principle?

The equilibrium that remains unaffected by pressure change is:

The catalyst iron employed in the Haber's process contains molybdenum, the function of which is

The rate constant of a reaction at temperature $200 \mathrm{K}$ is $10$ times less than the rate constant at $400 \mathrm{K}.$ What is the activation energy of the reaction?

The rate constant for forward reaction and backward reaction of the hydrolysis of ester are $1.1\times {10}^{-2}$ and $1.5\times {10}^{-3}$ per minute respectively. Equilibrium constant for the reaction is ${\mathrm{CH}}_3{\mathrm{COOC}}_2{\mathrm{H}}_5+{\mathrm{H}}_2\mathrm{O}\rightleftharpoons {\mathrm{CH}}_3\mathrm{COOH}+{\mathrm{C}}_2{\mathrm{H}}_5\mathrm{OH}$:

The equilibrium $2{\mathrm{SO}}_{2( \mathrm{g})}+{\mathrm{O}}_{2( \mathrm{g})}\rightleftharpoons 2{\mathrm{SO}}_{3( \mathrm{g})}$ shifts forward if:

For the system, $3\mathrm{A}+2\mathrm{B}\rightleftharpoons 2\mathrm{C},$ the expression for equilibrium constant $\mathrm{K}$ is:
