Question

Consider the following reaction:2H2(g) + O2(g) ↔ 2H2O(l)What is the equilibrium constant expression for the reaction?Select one:a.Keq= [H2]2 [O2] / [H2O]2 b.Keq = [H2O]2 / [H2]2 [O2]c.Keq = [H2]2 [O2]d.Keq = 1 / [H2]2 [O2]

Answer 1

`D`

Step-by-step explanation:

Here, we want to write the equilibrium constant expression for the given reaction

To generate this, we have to get the concentration of the product raised to the coefficient in the balanced reaction, divided by the concentration of the reactants raised the same way

We do not factor for solid and liquid states when writing the equilibrium constant expression

We have the expression written as follows:

`K_(eq)\text{ = }\frac{1}{[H_2]\placeholder{⬚}^2[O_2]}`
