Posted a question earlier but it was the wrong question. If anyone could help it would great if you could explain this would help also.

Question

Thanks
^ = subscript
Calculate ke for(equlibrium concentration below problem
2CO^2(g) + heat 2CO(g) + O^2
[0.103] [0.024] [1.18 x 10^2]

Answer 1

1. You have no arrow. How do we separate the reactants from the products? I assume it is
2CO2 + heat ==> 2CO + O2

2. You don't need to write ^ for subscripts. The ^ sign is reserved for exponents and on these boards it is understood that we can't write subscripts; therefore, NO2 means NO₂. 10^-3 means 10^-3.

3. What is the Ke expression? Isn't it
(CO)^2(O2)/(CO2)^2

4. If that second line you have denotes equilibrium concentrations, just plug into the appropriate boxes in the Ke expression (written in 3 above) and calculate.

Answer 2

Not sure, sorry.
