Question:

Arsenic can be extracted from its ores by first reacting the ore with oxygen (a process called roasting) to form solid As4O6, which is then reduced with carbon:

As406(s) + 6C(s) - As4(g) + 6CO(g)

Predict the direction of the shift of the equilibrium position for this reaction in response to each of the following changes in conditions.

a. Addition of CO

b. Addition or removal of C or As4O6

c. Removal of As4
