# 0.2 mole of A and 0.4 mile of B were reacted at a certain temperature and allowed to come to equilibrium . A+B---2AB The equilibrium mixture contained 0.1 mole of A, find Kc if volume of the container was 2 dm^3?

##### 1 Answer

#### Explanation:

I'll show my explanation in steps for your understanding

**1.** **First set balance the equation**

**2.** **Now write the equilibrium constant for the reaction**

**3.** As

**4.** As the volume of the container is

Conversionof ** #dm^3#** to

**litres**is necessary

**5.** **Calculate the molarities**

Conc. of A =

Conc. of B =

Conc. of A at equilibrium

**5.** **Set up an ICE table**

From the given information we know that the equilibrium amount of A is 0.05M. Thus

Solve for

**6.** **Solve for the equilibrium amounts of B and AB**

And we know the equilibrium amounts of A

**7.** **Now solve for #K_c#**

If you want

You can also calculate the

As
