Question
Map t Le Châtelier's principle states that A system at equilibrium will respond to a stress in a way that reduces that stress. In other words, if equilibrium is disturbed, the forward or reverse reaction will speed up until equilibrium is re-established. AB inialy wher are2 4 tiom s atoms and four AB molecules in the container and the system is at equilibrium Watch what happens if we add 4 more A atoms Pause Which of the following correctly explains what happened in the animation above? O O O O Adding A increased Q, so the net reaction proceeds to the right to decrease Q. Adding A increased Q, so the net reaction proceeds to the left to decrease C. Adding A decreased Q, so the net reaction proceeds to the right to increase Q. to the right to increase Q Adding A decreased Q, so the net reaction proceeds to the left to increase Q.Explanation / Answer
The correct explanation would be,
Adding A decreases Q, so the net reaction proceeds in the right to increases Q
Before adding A,
Q = 4 / 2 x 2 = 1
After adding 4 A
Q = 4 / 2 x 6 = 0.333
Q decreases, hence the reaction moves in forward direction
Now at equilibrium we have, 5 AM,, 5 A and 1 B
Q = 5 / 5 x 1 = 1
