Question

two systems pcl5 that gives pcl3+cl2 and cocl2 that gives co +cl2 are simultaneously in equilibrium in a vessel at constant volume if some co is introduced into the vessel than at new equilibrium the concentration of pcl5is​

Answer 1

Answer:

Answer 2

Answer:

PCl

5

is decreased

Explanation:

When CO is added to the above system, the second reaction will go backwards in accordance with Le Chatelier's principle and hence, the concentration of the common molecule, i.e., Cl

2

will also reduce.

So, to counteract the decreased concentration of chlorine, first equilibrium will go forward and hence, the concentration of PCl

5

will decreased.
