Consider the reaction,
`2Cl_(2)(g) + 2H_(2)O(g)hArr4HCl(g) + O_(2)(g)`
`DeltaH^(O) = + 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. State and explain the effect (increase, decrease, no change) of the operation in the left column (below) on the equilibrium value of the quantity in the right column. Each operation is to be considered separately. Temperature and volume are constant unless stated otherwise.
Increasing the volume of the container Number of moles of `H_(2)O`

Answer

decrease
