Among the following, the factors that favor the following forward reaction

${\mathrm{N}}_{2\left(\mathrm{g}\right)}+{\mathrm{O}}_{2\left(\mathrm{g}\right)}\to 2{\mathrm{NO}}_{\left(\mathrm{g}\right)}-43,200 \mathrm{K}.\mathrm{cal}$

For the reaction,

${\mathrm{N}}_{2\left(\mathrm{g}\right)}+{\mathrm{O}}_{2\left(\mathrm{g}\right)}\to 2{\mathrm{NO}}_{\left(\mathrm{g}\right)}-43,200 \mathrm{K}.\mathrm{cal}$

It is an endothermic reaction. At high temperature increase in the concentration of the reactants ${\mathrm{N}}_2 \mathrm{and} {\mathrm{O}}_2$

By increase in the concentration of ${\mathrm{N}}_2 \mathrm{and} {\mathrm{O}}_2$ , forward reaction favors. Decrease in the concentration of NO favors forward reaction.
