The equilibrium expression for a reaction is Ke = x2/V(a - x), what is true for the reaction.:
Correct answer: C. Decrease of pressure favors forward reaction.
- A. Increase of pressure favors forward reaction.
- B. Decrease of pressure favors backward reaction.
- C. Decrease of pressure favors forward reaction.
- D. Increase of volume favors backward reaction.
Explanation
Volume in denominator means no. of moles of product are greater than those of reactants.

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.
