Published on: August 13, 2026

Consider the reaction, 2Cl 2 (g) + 2H 2 O(g) 4HCl(g) + P 2 (g) ; Δ Hº = + 113 kJ

The four gases, Cl 2 , H 2 O, HCl and O 2 , are mixed and the reaction is allowed to come to equilibrium. Each operation is to be considered separately. Temperature and volume are constant unless stated otherwise. Report the number of operations in the left column which lead to increase in the equilibrium value of the quantity in the right column.

Increasing the volume of the container Number of moles of H 2 O

Adding O 2 Number of moles of H 2 O

Adding O 2 Number of moles of HCl

Decreasing the volume of the container Number of moles of Cl 2 (e) Decreasing the volume of the container Partial pressure of Cl 2 (f) Decreasing the volume of the container K C (g) Raising the temperature K C (h) Raising the temperature Concentration of HCl (i) Adding He Number of moles of HCl (j) Adding catalyst Number of moles of HCl
