Which one of the following conditions will favour maximum formation of the product in the reaction
$A_{2(g)} + B_{2(g)} \rightleftharpoons X_{2(g)}; \Delta_{r} H = -X \ kJ$

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:

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?

In the following reversible reaction $2SO_2(g) + O_2(g) \rightleftharpoons 2SO_3(g) + Q \ \text{cal}$. The most suitable condition for the higher production of $SO_3$ is:

On increasing temperature,the equilibrium constant of exothermic and endothermic reactions,respectively

What is true for the equilibrium reaction? $CH_3COOH + CH_3OH \rightleftharpoons[cat.]{} CH_3COOCH_3 + H_2O$
