\(\Delta{G}_f^0\) and \(\Delta{H}_f^0\) Fe(g) are 370.7 kJ mol-1 and 416.3 kJ mol-1 at 298 K, respectively. Assuming \(\Delta{H}_f^0\) is constant in the interval 250 K to 375. \(\Delta{G}_f^0\) (rounded off to the nearest integer) for Fe(g) at 375 K is:
1
359 KJ mol-1
2
338 KJ mol-1
3
325 KJ mol-1
4
310 KJ mol-1
