Answer:
(C) Decomposition
Decomposition is a process in decaying of rotting. The thermal decomposition of CO2 to CO and O2 is a possible way for the waste and utilization of CO2. However, this effect is confined by both the thermodynamic stability and the kinetic boundary. At 900 degrees C, this catalytic method achieves 100% of CO generation selectivity at 15.8% of CO2 changes.
