Solving problems that mix equilibrium ideas with gas laws
Sulfuric acid is essential to dozens of important industries from steelmaking to plastics and pharmaceuticals. More sulfuric acid is made than any other industrial
chemical, and world production exceeds 2.0 × 10¹¹ kg per year.
The first step in the synthesis of sulfuric acid is usually burning solid sulfur to make sulfur dioxide gas. Suppose an engineer studying this reaction introduces
1.5 kg of solid sulfur and 10.0 atm of oxygen gas at 400. °C into an evacuated 85.0 L tank. The engineer believes Kp = 0.087 for the reaction at this
temperature.
Calculate the mass of solid sulfur she expects to be consumed when the reaction reaches equilibrium. Round your answer to 2 significant digits.

Follow-up Question

what's this one?

When limestone (solid CaCO3) is heated, it decomposes into lime (solid CaO) and carbon dioxide gas. This is an extremely useful industrial process of great
antiquity, because powdered lime mixed with water is the basis for mortar and concrete the lime absorbs CO₂ from the air and turns back into hard, durable
2
limestone.
Suppose some calcium carbonate is sealed into a limekiln of volume 400. L and heated to 740.0 °C. When the amount of CaCO3 has stopped changing, it is
found that 3.37 kg have disappeared.
P
00.
Calculate the pressure equilibrium constant K this experiment suggests for the equilibrium between CaCO3 and CaO at 740.0 °C. Round your answer to 2
significant digits.

Note for advanced students: it's possible there was some error in this experiment, and the value it suggests for K does not match the accepted value.
