the values for delta H and delta S are C(graphite) + CO2(g) gives 2CO2(g) are 170 kJ and 170 J/k reslectively m. what is temperature at which reaction is spontaneous

According to Gibbs Helmhlotz equationG=H-TSTo find the spontaneous reaction temperature find the equilibrium condition.G=0So H-TS =0H=TST= HS     = 170× 103170   = 1000 KSo the temperature greater than 1000 K, will give the spontaneous condition.
