Consider this reaction: CaCo3(s) CaO(s) + CO2(g). What could be done to increase the rate of decomposition of CaCO3?
add CO2
remove CO2
decrease the pressure
decrease the temperature
increase the temperature

Respuesta :

CaCO₃(s)  ----T-----> CaO(s) + CO₂(g)
------------------------------------------------------------------------------
- remove CO₂
- decrease the pressure
- increase the temperature (it's an endothermic reaction)

Answer:

Remove CO2

Explanation:

As per Le Chatelier's principle, when a system at equilibrium is subjected to changes in temperature, pressure, concentration etc then the equilibrium will shift in a direction to undo the effect of the induced change.

The given reaction is:

CaCO3 (s) ↔ CaO(s) + CO2(g)

Therefore, if CO2 is removed then the equilibrium will shift to the right towards the products thereby increasing the rate of decomposition of CaCO3.
