Haber Process

Consider the reaction that occurs during the Haber process:

N2(g) + 3H2 (g) –> 2NH3 (g).

The equilibrium constant is 3.9×10^5 at 300 K and 1.2×10^-1 at 500 K. Calculate delta h reaction and delta s reaction.

I calculated delta H reaction to be -93 kJ and thats correct but I’m not sure how to calcul…
