Question
A 60.0 g sample of CaCO3 is heated to 950 K in a 1.00 L evacuated container, where it reacts according to the following equation:
CaCO3(s) ⇌ CaO(s) + CO2(g)
After equilibrium is attained, the pressure of CO2(g) is 30.0 mm Hg. When the experiment is repeated using 120.0 g CaCO3, what is the equilibrium pressure P?
A.
15.0 mm Hg ≤ P < 30.0 mm Hg
B.✓ Correct
P = 30.0 mm Hg
C.
30.0 mm Hg < P < 60.0 mm Hg
D.
P = 60.0 mm Hg
