In the decomposition of PCl5 represented by, PCl5 ⇋ PCl3 + Cl2, decrease in the pressure of the system will __________ the degree of dissociation of PCl5.
A. Increase
B. Decrease
C. Not alter
D. None of these
Answer: Option A
Solution(By Examveda Team)
Since the moles of reactants is less than the products by Le Chatelier's principle we can say decreasing the pressure will increases the dissociation of $$PC{l_5}.$$This Question Belongs to Chemical Engineering >> Chemical Engineering Thermodynamics
