5.2 Le Chatelier's Principle

Question 1

What is Le Chatelier’s Principle?

Answer 1

Is the equilibrium law. It can be used to predict the effect of a change in conditions.

Question 2

C(s) + O2(g) <=> 2CO(g)
#1 What will happen if O2 (g) is increased?
#2 What will happen if CO (g) is taken away?
#3 What will happen if C (s) is added?
#4 What will happen if pressure is increased?

Answer 2

#1 shift right.
#2 Shift right.
#3 Nothing since its a solid.
#4 If pressure is increased, volume will decrease. look at the mols of gas on either side of the reaction.  there is 1 mol of gas on the left and 2 mols of gas on the right. an increase in pressure or a decrease in volume will allow the right to react more and push the reaction left. Shift left.
