Question
Hydrogen chloride and oxygen react to form water and chlorine, like this: 4HCI(g)+02(g) 2H2O(g) +2C12(g) Suppose a mixture of HCL, o,, H20 and Cl, has come to equilibrium in a closed reaction vessel. Predict what change, if any, the perturbations in below will cause in the composition of the mixture in the vessel. Also decide whether the equilibrium shifts to the right or left. change in composition shift in equilibrium to the right to the left (none The pressure of BCI will The pressure of o2 will7 The pressure of HCI will to the left (none) Some O, is added. The pressure of H,O will 2 The pressure of H2O will The pressure of Cl, will to the right to the left (none) ? The volume of the vessel is ? O lype here to searchExplanation / Answer
Since the reaction has reached to an equillibrium state , any change in the conditions of the reaction , will cause the composition of the reaction mixture to change and shift the equillibrium to either side , accoridng to the Le Chatelier's Principle.
Some Cl2 is removed :
The pressure of HCl will decrease
The pressure of O2 will decrease
Equillibrium will shift to right.
Some O2 is added :
The pressure of HCl will decrease
The pressure of H2O will increase
The equillibrium will shift to right.
The volume of the vessel is increased
The pressure of H2O will decrease
The pressure of Cl2 will decrease
The equillibrium will shift to left.
