(a) For the reaction 3 A (g) ⇋ B (g) + 2 C (g), we start...

(a) For the reaction 3 A (g) ⇋ B (g) + 2 C (g), we start with just pure A (g) (there is no B (g) or C (g)). When equilibrium is reached, the sum of the partial pressures of B (g) and C (g) is 10 atm. The equilibrium constant for this reaction is 11. What is the partial pressure of A (g) at equilibrium? What was the initial pressure of A (g)?

(bWhat mass of phosphoric acid can be produced by the following reaction

          P4 (s) + 5 O2 (g) + 6 H2O (l) → 4 H3PO4 (s)

if we have 300 g of P4 (s), 400 g of O2 (g), and 500 g of H2O (l)?
