One step in the manufacture of specially purified nitrogen is the removal of small amounts of residual oxygen by passing the gas over copper gauze at approximately 500◦ C. The following reaction takes place:

(a) Assuming . that equilibrium is reached in this process, calculate the oxygen pressure in the purified nitrogen.

(b) What would be the effect of raising the temperature to 800◦ C? What if the temperature is lowered to 300◦ C? What is the probable reason for using 500◦ C?

(c) What would be the effect of increasing the pressure?
