For the reaction 2H2O(g)↽−−⇀2H2(g)+O2(g) the equilibrium concentrations were found to be [H2O]=0.250 M, [H2]=0.300 M, and [O2]=0.750 M. What is the equilibrium constant for this reaction?

1.08

Explanation:

Step 1:

Data obtained from the question. This includes:

[H2O] = 0.250 M

[H2] = 0.300 M

[O2] = 0.750 M

Equilibrium constant, K =?

Step 2:

Equation for the reaction.

2H2O(g) <=> 2H2(g) + O2(g)

Step 3:

Determination of the equilibrium constant.

The equilibrium constant for the above equation is written as fallow:

K = [H2]^2 [O2] / [H2O]^2

K = (0.3)^2 x 0.75 / (0.250)^2

K = 1.08

Therefore, the equilibrium constant for the above reaction is 1.08

water is used to store them because it would keep the radiation from getting out in the open and causing harm to the workers
