Carbon dioxide and water react to form methanol and oxygen, like this: 2CO2(g) + 4H2O(g) → 2CH3OH(l) + 3O2 (g)

At a certain temperature, a chemist finds that a 7.5L reaction vessel containing a mixture of carbon dioxide, water, methanol, and oxygen at equilibrium has the following composition:

Compound Amount
CO2 3.28g
H2O 3.86g
CH3OH 1.51g
O2 2.80g

Required:
Calculate the value of the equilibrium constant Kc for this reaction. Round your answer to 2 significant digits.

24x10³

Explanation:

2CO₂(g) + 4H₂O(g) → 2CH₃OH(l) + 3O₂ (g)

The equilibrium constant for this reaction is:

Kc =

The expression of [CH₃OH] is left out as it is a pure liquid.

Now we convert the given masses of the relevant species into moles, using their respective molar masses:

Then we calculate the concentrations:

Finally we calculate Kc:

answer: i have one answer

acids are substances that ionize (break off) in an aqueous solution to produce hydrogen (h+) ions

explanation:

hope this and sorry i could only come up with one answer!
