Answer to Question #206026 in General Chemistry for Fiona Yvonne Balia

Question

Write the equilibrium expression for the value of Q in the given reaction below.

a). 2 NOBr_(g)←→2 NO_(g)+Br_2(g)

b). 2 NO_(g)+Br_(2)(g)←→2 NOBr_(g)

c). NH_3(g)+HCl_(g)←→NH₄Cl_(s)

Answer 1

a) The equilibrium expression for the value of Q is-

Q=[NO]²[Br₂]/[NOBr]²

b)The equilibrium expression for the value of Q is-

Q=[NOBr]²/[NO]²[Br₂]

c)The equilibrium expression for the value of Q is-

Q=[NH₄Cl]/[NH₃][HCl]
