i need help for the three questions

For the reaction 2CO2(g)+5H2(g)C2H2(g)+4H2O(g) H=46.5kJ and S=124.8J/K The standard free energy change for the reaction of 1.73 moles of CO2(g) at 259K,1 atm would be kJ. This reaction is favored under standard conditions at 259K. Assume that H and S are independent of temperature. For the reaction C(s,graphite)+O2(g)CO2(g) G=395kJ and S=2.9J/K at 345K and 1atm. This reaction is favored under standard conditions at 345K. The standard enthalpy change for the reaction of 2.04 moles of C(s,graphite ) at this temperature would be kJ. For the reaction 2HBr(g)H2(g)+Br2(l) G=102kJ and H=72.6kJ at 257K and 1atm. This reaction is favored under standard conditions at 257K. The entropy change for the reaction of 2.01 moles of HBr(g) at this temperature would be J/K
