Calculate change in Gibbs free energy for the reaction CO(g) +1/2O2(g)-CO2(g) at 298.15 K. Calculate Change in Gibbs free energy reaction at 650 K assuming that enthalpy change in reaction is constant in the temperature interval of interest. What would you need to do if you could not make this assumption (explain,do not attempt a calculation)?
