The value of the equilibrium constant, Kc, at a certain temperature is 4.00 x 10-1. Would the reaction as represented by the chemical equation favor reactants or products? Enter P or R.

N2(g)+3H2(g) = 2NH3(g)

It favors products, of course.

You didn't write all of the reaction. It is
N2 + 3H2 ==> 2NH3 + heat
The reaction is exothermic.
Therefore, it you run the reaction at a higher temperature, R are favored; at a lower T, P are favored.
