Question

Use the reactions below and their equilibrium constants topredict the equilibrium constant for the equation, 2A(s)<--> 3D(g)       A(s) <-->1/2 B(g) + C(g)    K1=.0334              3D(g)<--> B(g) +2C(g)     K2= 2.35 Use the reactions below and their equilibrium constants topredict the equilibrium constant for the equation, 2A(s)<--> 3D(g)       A(s) <-->1/2 B(g) + C(g)    K1=.0334              3D(g)<--> B(g) +2C(g)     K2= 2.35       A(s) <-->1/2 B(g) + C(g)    K1=.0334              3D(g)<--> B(g) +2C(g)     K2= 2.35

Explanation / Answer

The Equilibrium constant for this is , K1 = ( [C] [B] 1/2 )   /[A]    ---(1)       3D(g)<--> B(g) +2C(g)     K2= 2.35 The Equilibrium constant for this is , K2 = ([C]2 [B ]   )   / [D]3    -----(2) 2A(s) <--> 3D(g)   : K = ? The Equilibrium constant , K = [ D] 3 / [A]2 this can be arranged as      K= { ( [C] [B ] 1/2 )   / [A] ) 2 } / { ([C]2 [B ]   )   / [D]3   }                                            = K1 2 / K2                                            = 0.0334 2 / 2.35                                            = 4.747
