2HF ⇌ H2 + F2 PCI5 ⇌ PCI3 + Cl2The statement that is false about the Ke of both the reactions is;
Correct answer: D. Unaffected by ∆T
- A. Unaffected by ∆V
- B. Unaffected by ∆P
- C. A, B
- D. Unaffected by ∆T
Explanation
Most of the reactions involve heat changes so they are affected by ∆T. Option d is the correct option .The reaction will be affected by ∆ T, changing the position of equilibrium depending on whether the reaction is endothermic or exothermic.

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.
