Question

Write an equilibrium constant expression for each of the following reactions. If gases are involved, write the expression in terms of partial pressures of the following reactions IT Enclose pressures in parentheses and do NOT write the chemical formula as a subscript. For example, enter (PNH) as (PNH). the numerator or denominator is 1, please enter . For example, enter (PHIeither If either (a) 2PF3(g) +02(g) 2POF3(g) Kp (b) 6 Fe2O3(s) 4 Fe3O4(s) +02(g) Kp (c) BaSO4(s) Ba2+(aq) SO42-(aq) t + Previous Next

Explanation / Answer

a. 2PF3(g) + O2(g) -----------> 2POF3(g)

    Kp   = P2POF3/P2PF3 PO2

b. 6Fe2O3(s) --------------> 4Fe3O4(s) + O2(g)

     Kp = PO2

c. BaSO4(s) ---------------> Ba^+2 (aq) + SO4^2- (aq)

       Kc = [Ba^+2][SO4^2-]

d. C6H14(l) ---------------> C6H14(g)

      Kp = PC6H14
