In the manufacture of ammonia by Haber's process,$N_{2(g)} + 3H_{2(g)} \rightleftharpoons 2NH_{3(g)} + 92.3 \ kJ$,which of the following conditions is unfavourable?

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?

The chemical equilibrium of a reversible reaction is not influenced by

Which of the following conditions is used to obtain atomic $Cl$ from molecular $Cl_2$?

Higher yield of $NO$ in the reaction $N_{2(g)} + O_{2(g)} \rightleftharpoons 2 NO_{(g)}$ 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 yield of product in the reaction $A_{2(g)} + 2B_{(g)} \rightleftharpoons C_{(g)} + Q \ kJ$ would be high at
