Nitrogen and oxygen react to form nitrogen monoxide, like this:

$N_2(g)+O_2(g)2NO(g)$

The reaction is endothermic. Suppose a mixture of $N_2,O_2$ and $NO$ has come to equilibrium in a closed reaction vessel. Predict what change, if any, the perturbations in the table below will cause in the composition of the mixture in the vessel. Also decide whether the equilibrium shifts to the right or left.
