# At a particular temperature a 2.00-L flask at equilibrium contains 2.80 10-4 mol N2, 2.50 10-5 mol O2, and 2.00 10-2 mol N2O. How would you calculate K at this temperature for the following reaction: 2 N2(g) + O2(g) --> 2 N2O(g)?

##### 1 Answer

#### Answer:

#### Explanation:

In an equilibrium reaction, the equilibrium constant

The stoichiometric coefficients in the equation are used as exponents on the concentrations. (See how the equilibrium equation references

To find the concentrations (molarity), divide the mole amounts by the volume.

The equilibrium constant is unitless.
