Correct answer

Step-by-step solution

aligned & N ₂( ~g )+3 H ₂( ~g ) 2 NH ₃ & H ^ =- ve & ~S ^ =- ve aligned (As gaseous moles decreases). (1) As temperature increases - H _R^0 T , decreases (2) G ^ =- RT K _ eq R K _ eq =- G ^0 ~T (on increasing temperature in exothermic reaction K _ eq decreases) H ^ and S ^ are almost constant with temperature.
