Raising the temperature of a reversible chemical reaction :

In the reaction ${A_2}(g) + 4{B_2}(g)\leftrightharpoons2A{B_4}(g),\Delta H < O$ the formation of $A{B_4}$ will be favoured at

For the reaction,

${\rm{PC}}{{\rm{l}}_3}\left( {\rm{g}} \right) + {\rm{C}}{{\rm{l}}_2}\left( {\rm{g}} \right)\;\leftrightharpoons\;{\rm{PC}}{{\rm{l}}_5}\left( {\rm{g}} \right)$ the position of equilibrium can be shifted to the right by

The law of mass action was enunciated by

The equilibrium constant of the following are, $I.\,{N_2} + 3{H_2}⇋2N{H_3};\,\,{K_1}$ , $II.\,{N_2} + {O_2}⇋2NO;\,\,{K_2}$, $III.\,{H_2} + \frac{1}{2}{O_2}⇋{H_2}O;\,\,{K_3}$. The equilibrium constant (K) of the reaction $2N{H_3} + \frac{5}{2}{O_2}⇋2NO + 3{H_2}O$ will be

The reaction quotient $\left( Q \right)$ for the reaction is given by: ${{\rm{N}}_2}\left( {\rm{g}} \right) + 3{{\rm{H}}_2}\left( {\rm{g}} \right)\leftrightharpoons2{\rm{N}}{{\rm{H}}_3};Q = \frac{{{{\left[ {{\rm{N}}{{\rm{H}}_3}} \right]}^2}}}{{\left[ {{{\rm{N}}_2}} \right]{{\left[ {{{\rm{H}}_2}} \right]}^3}}}$The reaction will proceed from right to left if:

${\rm{C}}{{\rm{H}}_3}{\rm{COOH}}\left( l \right) + {{\rm{C}}_2}{{\rm{H}}_5}{\rm{OH}}\left( l \right)\;\leftrightharpoons\;{\rm{C}}{{\rm{H}}_3}{\rm{COO}}{{\rm{C}}_2}{{\rm{H}}_5}\left( l \right) + {{\rm{H}}_2}{\rm{O}}\left( l \right)$In the above reaction, one mole of each of acetic acid and alcohol are heated in the presence of little conc. ${{\rm{H}}_2}{\rm{S}}{{\rm{O}}_4}$. On equilibrium being attained

In a flask, colourless ${{\rm{N}}_2}{{\rm{O}}_4}$ is in equilibrium with brown coloured ${\rm{N}}{{\rm{O}}_2}$. At equilibrium, when the flask is heated at 100\,^\circ C the brown colour deepens and on cooling it becomes less coloured. The change in enthalpy $\Delta H,$ for the system is :

In the reaction $H_2(g) + I_2(g) \rightleftharpoons 2HI(g)$, at equilibrium, adding more $H_2$ will:

For the reaction, ${N_2}\;\; + \;3{H_2}\;\leftrightharpoons\;2N{H_3};$ in a vessel, after the addition of equal number of mole of ${N_2}$ and ${H_2}$, equilibrium state is formed. Which of the following is correct?

The equilibrium reaction that is not influenced by volume change at constant temperature is
