For the reaction,$A_{(g)} + B_{(g)} \rightleftharpoons C_{(g)} + D_{(g)}$; $\Delta H = Q \ kJ$,the equilibrium constant cannot be disturbed by

In what manner will an increase of pressure affect the following equilibrium equation?
$C_{(s)} + H_2O_{(g)} \rightleftharpoons CO_{(g)} + H_{2(g)}$

$Le-Chatelier$'s principle is not applicable to:

The $\%$ yield of ammonia as a function of time in the reaction $N_{2(g)} + 3H_{2(g)} \rightleftharpoons 2NH_{3(g)}$,$\Delta H < 0$ at $(P, T_1)$ is given below. If this reaction is conducted at $(P, T_2)$,with $T_2 > T_1$,the $\%$ yield of ammonia as a function of time is represented by:

Describe the effect of:
$(a)$ Addition of $H_2$
$(b)$ Addition of $CH_3OH$
$(c)$ Removal of $CO$
$(d)$ Removal of $CH_3OH$ on the equilibrium of the reaction:
$2H_{2(g)} + CO_{(g)} \longleftrightarrow CH_3OH_{(g)}$

The effect of the addition of helium gas to the following reaction in an equilibrium state is:
