How do you calculate Ke for 2 SO2 (g) + O2 (g) ↔ 2 SO3 (g) + heat
[0.0500] [0.0500] [0.103]
Are those equilibrium concns. If so, then
Ke = (SO3)^2/(SO2)^2*(O2)
Substitute the number you have, if those are equilibrium concns, and punch the calculator.
To calculate the equilibrium constant (Ke) for the given reaction, you need to use the concentrations of the reactants and products at equilibrium. The given concentrations are:
[SO2] = 0.0500 M (concentration of SO2 at equilibrium)
[O2] = 0.0500 M (concentration of O2 at equilibrium)
[SO3] = 0.103 M (concentration of SO3 at equilibrium)
The equation for Ke in this case is:
Ke = ([SO3]^2) / ([SO2]^2 * [O2])
Now, substitute the given concentrations into the equation:
Ke = ([0.103]^2) / ([0.0500]^2 * [0.0500])
Simplifying this expression:
Ke = (0.010609) / (0.000125)
Finally, divide to calculate Ke:
Ke = 84.872
Therefore, the equilibrium constant (Ke) for the given reaction is approximately 84.872.
