Answer #1

1)

a) Le Chatelier's principle states that any change to a system at equilibrium will adjust to compensate for that change.

When Extra A is added the equilibrium shifts to right.

because According to Le Chatelier, the position of equilibrium will move in such a way as to counteract the change. In this case, the equilibrium position will move so that the concentration of A decreases again by reacting it with B to form more C. Therfore the equilibrium moves to the right

b)

Extra B is added then the equilibrium shifts to right

same above reason

c) If Some C is removed then the equilibrium shifts to right

2)

When the rates are equal, equilibrium has occurred. The reaction appears to have stopped, and the total amount of products and reactants remains stable. Chemical reactions never really stop, but theyno longer make any progress once the forwards and backwards reactions are occurring at the same rate.
