Answer:
Explanation:
H2+ CO2 > H2O + CO
initial concentration of the each reactant is 0.8 mole / 5 litre or 0.16 mol/L . Let X mol/ L of each reactant combines to produce X mole/L of each product.
K = [ H2O] [ CO] / [ H2] [CO2 ]
4 = X × X / 0.16-X × 0.16 -X = X^2 / (0.16-X)^2
Taking square root of both sides
2 = X / 0.16 -X
0.32 — 2X = X
X = 0.32/3
Equilibrium concentration of CO2
= 0.16 — 0.32/3 = 0.16/3 mol/L
