Chemistry - Chemical Equilibrium Question with Solution | TestHub
is heated in a closed vessel to establish the equilibrium, . The equilibrium can be allowed to shift in forward direction
Options:(select one or more)
Answer:
Solution:
CaCO₃(s) CaO(s) + CO₂(g)
As the amount of solid in the closed vessel increases, the partial pressure of the gas increases.
Thus, . Therefore, adding CaO(s) causes the reaction to move in the backward direction. As CaO(s) is removed, , and the reaction will move in the forward direction.
The equilibrium shifts in the forward direction by adding a small amount of water to the system. The water reacts with CaO, forming Ca(OH)₂, which will reduce the pressure of CO₂ by reacting with it to form CaCO₃.
The equilibrium will also shift in the forward direction by increasing the volume of the reaction vessel because it will reduce the pressure of CO₂.
