# Complete reaction PbO+C ->Pb+? Some sources suggest CO_2 while others CO. Do they exist in equilibrium?

This describes the reaction when lead oxide is heated in a furnace with charcoal. Both probably result, but more sources mention carbon dioxide than carbon monoxide.

Hence,

$2 P b O \left(s\right) + C \left(s\right) r i g h t \le f t h a r p \infty n s 2 P b \left(s\right) + C {O}_{2} \left(g\right)$

or

$P b O \left(s\right) + C O \left(g\right) r i g h t \le f t h a r p \infty n s P b \left(s\right) + C {O}_{2} \left(g\right)$

are more representative of what's happening.

And, regarding equilibrium: every reaction is in equilibrium, but some lie so far toward one side they are simplified with one arrow. I would hypothesize that this reaction proceeds backwards at such a slow rate we can represent the reaction with a one-way arrow.
