Worksheet: Le Chatelier's Principle Name______________ CHEMISTRY: A Study of Matter © 2004, GPB 12.11 If a system at equilibrium is subjected to a ____________ , the equilibrium is displaced in the direction that relieves the ____________. • A stress is defined as any change which could affect the ____________ of either or both the forward and/or reverse reaction. • When, because of an applied stress, the forward reaction is faster than the reverse reaction, the system is said to shift to the (right, left). As a result, the [products] will (increase, decrease) and the [reactants] will (increase, decrease). • When, because of an applied stress, the reverse reaction is faster than the forward reaction, the system is said to shift to the (right, left). As a result, the [products] will (increase, decrease) and the [reactants] will (increase, decrease). In simpler terms: If anything is added to a system at ____________, the system will try to consume whatever was ____________. If anything is removed from a system at equilibrium, the system will try to replace whatever was ____________. So, the reaction is favored away from what is (added, removed) and toward what is (added, removed). 1. In the following reaction, will the [H2] increase or decrease when equilibrium is reestablished after these stresses are applied?
N 2 (g) + 3 H 2 (g) 2 NH 3 (g) + 22 kJNH3(g) is added ________ N2(g) is removed ________ pressure is increased ________ temperature is increased ________ 2. Note reaction:
2 NO (g) + H
2 (g) N 2O (g) + H
2O (g) + 36 kJ
In which direction, left or right, will the equilibrium shift if the following changes are made? NO is added ________ the system is cooled ________ H2 is removed ________ pressure is increased ________ N2O is added ________ H2 is removed ________
Worksheet: Le Chatelier's Principle Name______________ CHEMISTRY: A Study of Matter © 2004, GPB 12.12 3. In this reaction:
CO 2 (g) + H 2 (g) + heatCO (g) + H
2 O (g)a. Is heat absorbed or released by the forward reaction? ____________ b. In which direction will the equilibrium shift if these changes are made? CO is added ________ temperature is increased ________ CO2 is added ________ system is cooled ________ H2 is removed ________ pressure is increased ________ catalyst is added ________ 4. In this reaction:
2 NO (g) + H
2 (g) N 2O (g) + H
2O (g) + heat
What will happen to the [H2O] when equilibrium is reestablished after these stresses are applied? temperature is increased ________ a catalyst is added ________ pressure is decreased ________ NO is added ________ N2O is removed ________ 5. How would an increase in pressure affect the [H2] in the following reactions?
2 H 2 (g) + O 2 (g) 2 H 2 O (g) __________ 4 H 2 (g) + Fe 3 O 4 (s)
