Question

The equation for an equilibrium reaction is A +B      AB. Following Le Chatelier'sprinciple, if the concentration of "A" is increased,then (a) stress and equilibrium are not affected (b) the equilibrium shifts to the left (c) the equilibrium shifts to the right (d) a smalleer concentration of products is formed The equation for an equilibrium reaction is A +B      AB. Following Le Chatelier'sprinciple, if the concentration of "A" is increased,then (a) stress and equilibrium are not affected (b) the equilibrium shifts to the left (c) the equilibrium shifts to the right (d) a smalleer concentration of products is formed

Explanation / Answer

Adding A to the system makes your reaction "left heavy" so yourequilibrium will shift to the right to consume the extra A added tothe system in order to maintain your equilibrium. The system wantsto stay the same and when you add more A, you're changing thesystem so that is why A is consumed and you get more of yourforward reaction to make up for the extra A.
