Here is the exercise; I'd like to check my answer with you (and to receive some help, if possible, on the part of the problem I didn't manage to solve
):
– • –
FeO
(g) is reduces to Fe
(s) treating it with CO
(g), according to the following equation:
Knowing that at T temperature the equilibrium constant of the reaction is 5, calculate the volume of CO needed to produce 100kg of Fe
(s) , working at T=400 K
[M(Fe)=55.8]
– • –
As the equilibrium is heterogeneous I write K
eq without including solid species involved (I suppose that the reaction occurs in a closed environment with a fixed volume):
Now, x must be equal to number of moles of iron produced so i can calculate the number of moles of CO
g needed:
Now I don't know how to get the volume needed starting from this, I tried using the K
p but the only thing I found out is this:
Have you got any ideas?
