Question

1. Is the Boudouard Reaction exothermic or endothermic?

2. Is the reaction spontaneous at low temperatures?

3. Is the reaction spontaneous at high temperatures?

4. At what temperature the reaction becomes spontaneous?

5. The vant Hoff's equation works if there is no (or very weak) temperature dependence of change of standard enthalpy and standard entropy on temperature. Does your vant Hoff's graph support this assumption?
