Chemical Equilibrium

At a certain temperature Kc = 25 and a reaction vessel contains a mixture with the following concentrations: [H2] = 0.10 M, [Br2] = 0.10 M and [HBr] = 0.50 M. Which of the following statements concerning the reaction and the reaction quotient, Q, is true?

H2(g) + Br2(g) 2HBr(g)

a. Q = Kc
b. Q < Kc; more HBr will be produced.
c. Q < Kc; more H2 and Br2 will be produced.
d. Q > Kc; more HBr will be produced.
e. Q > Kc; more H2 and Br2 will be produced.

Answer: a. Q = Kc
