For the reaction X + Y ⇌ ZKc = 6 x 10^-7; then at equilibrium

Correct answer: B. Both X and Y would be favoured

  • A. Z would be favoured
  • B. Both X and Y would be favoured
  • C. X would be favored
  • D. X, Y and Z would be favored

Explanation

Given the small value of Kc, the reaction predominantly favors the reactants (X and Y). This means that X and Y are more likely to be present in higher concentrations at equilibrium, while Z would be present in a lower concentration.

About Chemical Equilibrium

Reversible reactions reach dynamic equilibrium when forward and reverse rates become equal, and Le Chatelier's principle predicts the effect of changing concentration, pressure or temperature. The chapter also covers solubility product, the common ion effect, buffer action and the conditions used in Haber's process, with equilibrium shifts distinguished from changes in the equilibrium constant.
