Show answer
The equilibrium will shift to the right (towards the products).
Also accept: Shifts to the right; Shifts towards the products; Moves right; Moves to the right; Equilibrium moves to the right
Common mistakes: Shifts to the left

A1 · 1 mark · States that the position of equilibrium shifts to the right/towards the products.
Worked solution
Adding more B increases the concentration of a reactant, so the equilibrium responds by shifting to the right to use up the extra B and form more C and D.
