Which of the following factors will favour the reverse reaction in a chemical equilibrium?

In the $N_2 + 3H_2 \rightleftharpoons 2NH_3$ reversible reaction,an increase in pressure will favour:

Le Chatelier's principle is applicable only to a

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:

Consider the following equation:
$2 SO_{2(g)} + O_{2(g)} \rightleftharpoons 2 SO_{3(g)}, \Delta H = -190 \ kJ$
The number of factors which will increase the yield of $SO_3$ at equilibrium from the following is $.............$.
$A.$ Increasing temperature
$B.$ Increasing pressure
$C.$ Adding more $SO_2$
$D.$ Adding more $O_2$
$E.$ Addition of catalyst

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