Question

As shown in Table 15.2 in the textbook, KpKp for the equilibrium
N2(g)+3H2(g)⇌2NH3(g)N2(g)+3H2(g)⇌2NH3(g)
is 4.51×10−54.51×10−5 at 450 ∘C∘C. For each of the mixtures listed here, indicate whether the mixture is at equilibrium at 450 ∘C∘C. If it is not at equilibrium, indicate the direction (toward product or toward reactants) in which the mixture must shift to achieve equilibrium.

A. 98 atmatm NH3NH3, 45 atmatm N2N2, 55 atmatm H2H2
98  , 45  , 55  
a. yes, mixture is at equilibrium
b. no, mixture must shift toward products to achieve equilibrium
c. no, mixture must shift toward reactants to achieve equilibrium

B.57 atmatm NH3NH3, 143 atmatm N2N2, no H2H2

57  , 143  , no 
a.yes, mixture is at equilibrium
b.no, mixture must shift toward products to achieve equilibrium
c.no, mixture must shift toward reactants to achieve equilibrium
