For a reaction,if $K_p > K_c$,then the forward reaction is favored by ..... $(T > 15 \ K)$

For the reaction at equilibrium
$N_{2(g)} + 3H_{2(g)} \rightleftharpoons 2NH_{3(g)}$
On addition of an inert gas at constant pressure and constant temperature,which of the following changes is $NOT$ observed?

For the reaction $2SO_2(g) + O_2(g) \rightleftharpoons 2SO_3(g)$,$\Delta H^o = -198 \, kJ$. According to Le Chatelier's principle,the favorable conditions for the forward reaction are:

When a sample of $NO_2$ is placed in a container,this equilibrium is rapidly established: $2NO_{2(g)} \rightleftharpoons N_2O_{4(g)}$. If this equilibrium mixture is a darker colour at high temperatures and at low pressure,which of these statements about the reaction is true?

For the equilibrium system $CO_{2(s)} \rightleftharpoons CO_{2(g)}$,$\Delta H = +ve$,what happens if the temperature is decreased?

For the reversible reaction,
$N_{2(g)} + 3H_{2(g)} \rightleftharpoons 2NH_{3(g)} + \text{heat}$
The equilibrium shifts in the forward direction:
