At high temperatures, solid calcium carbonate (M = 100.09) is in equilibrium with solid calcium oxid — Equilibrium Chemistry Question
Question
At high temperatures, solid calcium carbonate (M = 100.09) is in equilibrium with solid calcium oxide and carbon dioxide gas.
CaCO3(s) ⇌ CaO(s) + CO2(g)
Into an evacuated 30.0 L chamber maintained at 1200 K is introduced 3.0 g solid CaCO3. After the system is allowed sufficient time to equilibrate, the pressure is 0.10 bar. What will the total pressure be at equilibrium if an additional 3.0 g CaCO3 is added to the chamber?
A.
0.10 bar
B.
0.14 bar
C.
0.20 bar
D.✓ Correct
