Observe the following equilibrium at $T(K)$:
$H_{2(g)} + I_{2(g)} \rightleftharpoons 2HI_{(g)}$
Which one of the following does not disturb the above equilibrium?

The following reaction occurs in the blast furnace where iron ore is reduced to iron metal:
$Fe_2O_{3(s)} + 3CO_{(g)} \rightleftharpoons 2Fe_{(l)} + 3CO_{2(g)}$
Using Le Chatelier's principle,predict which one of the following will not disturb the equilibrium.

Which of the following equilibrium is not shifted by an increase in pressure?

Higher yield of $NO$ in $N_{2(g)} + O_{2(g)} \rightleftharpoons 2 NO_{(g)}$ can be obtained at [ $\Delta H$ of the reaction $= +180.7 \ kJ \ mol^{-1}$ ]
$A.$ Higher temperature
$B.$ Lower temperature
$C.$ Higher concentration of $N_2$
$D.$ Higher concentration of $O_2$
Choose the correct answer from the options given below:

The rate of reaction of which of the following is not affected by pressure?

When $I_2$ dissociates to its atomic form the following reaction occurs:
$I_{2(g)} \rightleftharpoons 2I_{(g)} ; \Delta_r H^o = +150 \ kJ \ mol^{-1}$
The forward reaction is favoured at:
