Question

Q7 Determine the concentration of Co, which will be in equilibrium with 2.5x
10-2 mol L-lof CO at 100°C for the reaction.
Fe(s) + CO(g = Fe(s) + CO2(g), K.-5.0
a) 12.5x 10-2M
b) 15.5 x 10-2M
c) 12.5 x 10-M
d) 15.5 x 10-M​

Answer 1

Answer:

a)

Explanation:

First of all the reaction is wrong, it should be

FeO + CO = Fe + CO2. and the values of K is not clear. Other thing is that it is told to determine the conc of CO and the given conc is also of CO, one should be co2 but which one?

now K= conc of CO2/conc of CO

or 5 = conc of co2/2.5x10^-2

or Conc of CO 2= 0.0025x5=12.5x10^-2M
