For a reaction proceeding with increase in no. of moles, which of these can affect in more than one ways.

Correct answer: C. Change in T (Temperature)

  • A. Increase in V (Volume)
  • B. Increase in P (Pressure)
  • C. Change in T (Temperature)
  • D. Catalyst

Explanation

Increase in volume - YES (affects equilibrium position and concentration/rate)Increase in pressure - YES (affects equilibrium position and rate)Change in temperature - YES (affects equilibrium constant and rate)Catalyst - NO (only affects rate, not equilibrium)

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.
