In 1.33L container, 4.20 AB3, is heated to 400C, and 2.98x10-2(negative 2) moles of A is present at equilibrium.
AB3(g) <----> A(g)+ 3B(g)
(a.) Write the expression for K
(b.) Calculate the equilibrium concentration of the following gases
(c.) Calculate K
(d.) Calculate the partial pressure of A
(e.) For the reaction:
A(g) + 1/3B(g)<----> AB3(g) calculate the K value.

4.20 moles of WHAT. moles? buckets? rail cars? I will assume moles but it may be grams and I won't waste my time until you get back with additional information.
