Answer:
0.713atm for CO and 0.287atm for CO₂
Explanation:
Based on the reaction:
FeO(s) + CO(g) ⇋ Fe(s) + CO₂(g)
Kp is defined as:
= 0.403
When 1.00 atm of CO react with an excess of FeO, the pressures in equilibrium are:
PCO = 1.00atm - x
PCO₂ = x
<em>Where x represents the reaction coordinate.</em>
Replacing in Kp expression:
0.403 - 0.403x = x
0.403 = 1.403x
0.287atm = x
Thus, pressures in equilibrium are:
PCO = 1.00atm - x = <em>0.713atm</em>
PCO₂ = x = <em>0.287atm</em>
