The following reaction is a step in the commercial production of sulfuric acid.

2SO2(g) + O2(g) 2SO3(g)

The equilibrium constant is very high at room temperature, but the reaction is very slow. It must be run at high temperatures to achieve a reasonable rate of reaction. However the equilibrium constant decreases as temperature increases. Calculate Kc at 807 °C from the following concentration data:
[SO3] = 0.016 M
[SO2] = 0.029 M
[O2] = 0.0058 M

I calculated 52.48 for Kc I don't understand how to figure it out for a certain temperature.

  • Chemistry -

    You did it at 807C.

  • Chemistry -

    so is that the right answer? Because my online assignment keeps telling me that it is incorrect

  • Chemistry -

    I didn't work it out

    2S02+O2>>2SO3
    k=[SO3]^2/[SO2]^2[O2]

    I didn't get your answer.
