The equilibrium constant for 2H2O---> 2H2 + O2 reaction is calculated as follows
Keg ={ (H2)^2 (O2)}/ (H2o)^2
that is{ (0.370^2) x ( 0.750)} / (0.250^2)= 1.643
Keg ={ (H2)^2 (O2)}/ (H2o)^2
that is{ (0.370^2) x ( 0.750)} / (0.250^2)= 1.643
Answer:
Kc = 1.28
Explanation:
Let's consider the following reversible reaction.
H₂O(g) ⇄ H₂(g) + 0.5 O₂(g)
The equilibrium constant (Kc) is the product of the concentrations of the products raised to their stoichiometric coefficients divided by the product of the concentration of the reactants raised to their stoichiometric coefficients.
[tex]Kc=\frac{[H_{2}][O_{2}]^{0.5}}{[H_{2}O]} =\frac{(0.370).(0.750)^{0.5}}{0.250} =1.28[/tex]
