Some C6H5CH2OH is allowed to dissociate into C6H5CHO and H2 at 523 K. At equilibrium, [C6H5CH2OH] = 0.325 M, and [C6H5CHO] = [H2] = 6.50×10-2 M. Additional C6H5CHO is added so that [C6H5CHO]new = 0.119 M and the system is allowed to once again reach equilibrium.

  • C6H5CH2OH(g) <-------> C6H5CHO(g) + H2(g) K = 1.30×10-2 at 523 K


(a) In which direction will the reaction proceed to reach equilibrium?

(b) What are the new concentrations (M) of reactants and products after the system reaches equilibrium?

    Use an ICE table to calculate K A mixture of H, and I, is allowed to react at 661 K H2(g) + 12(g) +2HI(g) The initial concentration of the reactants are (Hy] -0.1960 M and [1,1 -0.2130 M. After the system reaches equilibrium, it is found that the l, concentration has decreased to 0.0506 M. Based on these data, determine the value of the equilibrium constant, K, for this reaction.
