A particular reaction has a Ho value of 147 kJ and So of 121

A particular reaction has a ?H^o value of -147 kJ and ?S^o of 121 J/mol K at 298 K. Calculate ?G^o at 211 K in kJ, assuming that ?H^o and ?S^o hardly change with temperature

del G=del H-TdelS we can assume del H and del S to be constant over temperature

so del G at 211 k=-147000-211*121=172531 J= 172.531 KJ
