What will happen to the following equilibrium if Cl2 was removed ?
4HCI(9) + O2(9) = 2012(9) + 2H20(9)

The following equilibrium will shift in the direction of the product:

Given

Reaction

4HCl + O₂ → 2H₂O + 2Cl₂

Cl₂  was removed

Required

Equilibrium changes

Solution

Reaction = - action

adding the products ⇒ Shifts in the direction of the reactants

reducing the products ⇒Shifts in the direction of the products

Cl₂ as a product, so if Cl₂ is taken or reduced, the reaction will try to maintain system equilibrium by moving to the right (product formation) ⇒ Shift in the direction of the product:

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current
