Among the following, factor that favor the following forward reaction is

 $2{\mathrm{NO}}_{2\left(\mathrm{g}\right)}\to {\mathrm{N}}_2{\mathrm{O}}_{4\left(\mathrm{g}\right)}+14.6 \mathrm{K}.\mathrm{cal}$

The chemical reaction is

There is a decrease in volume from 2 V to 1 V in a forward direction.

As heat is released in the given reaction, it is an exothermic. So, the favorable conditions of the reaction in a forward direction are high pressure and low temperature.
