iron oxide

The sparks from a steel grinder are molten iron. The iron reacts with oxygen to form iron III oxide.

A chemistry student wants to understand the effect of changing the volume on the equilibrium position of a chemical reaction. Accordingly, the student designs an experiment where they mix 0.2 mol of nitrogen gas with 0.1 mol of hydrogen gas in a 1 L container and allow them to react to form ammonia gas. If the reaction reaches equilibrium at a certain temperature and the volume of the container is suddenly decreased to 0.5 L, what will be the effect on the concentration of ammonia gas?

Design a chemical reactor to produce 500 kg of ethylene oxide per hour from ethylene and oxygen gases. Assume the reaction occurs isothermally, and the reactor operates at 3 atm and 250°C. The conversion of ethylene to ethylene oxide is 90%, and the selectivity of ethylene oxide is 97%. You can use either a plug-flow reactor or a continuous stirred-tank reactor. Determine the volume and dimensions of the reactor, and also its cost, assuming a stainless steel construction.
