The last time I taught equilibrium to my Year 13s, I had a number of bright, inquisitive students who got frustrated with the idea that for an equilibrium between A + B (see below) increasing the concentration of A would shift the position of equilibrium to the right but Kc would be unaffected. I tried showing...
