The equilibrium between three substances, A, B and C is shown below. A(g) + B(g) C(g)

Question:

The equilibrium between three substances, A, B and C is shown below.

A(g) + B(g) ⇋ C(g)

Initially there were 0.1mol of a and 0.2mol of B in the reaction mixture. a and B reacted together to produce an equilibrium mixture containing 0.04mol of c. The total volume of the mixture was 2.00 dm³.

a. Calculate the number of moles of a and B at equilibrium.

b. Calculate the concentrations of a, B and c at equilibrium.

c. i. Write the equilibrium expression for K_c.
ii. Calculate the value of K_c and give the units.
