##### 1 Answer

The equilibrium concentration of

Before doing any actual calculations, take a look at the value of the equilibrium constant,

Since *smaller than 1*, the equilibrium will lie to the **left**, meaning that, at equilibrium, the mixture will contain more reactant than products.

This implies that the equilibrium concentration of the products will be significantly smaller than that of the reactant,

Use an **ICE table** to help you with the calculations

**I**.....0.150.............0............0

**C**....(-

**E**....0.150-2x.........x...........x

The equilibrium constant is equal to

You acn solve this by taking the square root of both sides of the equation to get

This is equivalent to

Since

Notice that the initial prediction turned out to be correct. The equilibrium concentrations of the products are indeed smaller than that of the reactant.
