. Consider the endothermic reaction: Fe3+(aq) + Cl-(aq) → FeCl2+(aq). Use Le Châtelier’s principle to predict how the equilibrium concentration of the complex ion FeCl2+ will change when: (3.1) Fe(NO3)3 is added (3.2) Cl- is precipitated as AgCl by addition of AgNO3 (3.3) The temperature is increased (3.4) A catalyst is added (3.5) The pressure of the system is increased

Using Le Chatelier's Principle, What will happen to the number of moles of SO3 in equilibrium with SO2 and O2 in the reaction? 2SO3(g) ⇌ 2SO2(g) + O2(g) in each of the following cases: 1. Oxygen is added to reaction container. 2. The pressure is increased by decreasing the volume of the reaction container. 3. In the rigid container (i.e. constant volume), the pressure is increased by adding argon gas. 4. The temperature of the reaction container is decreased (Note:...

Equilibrium and Le Chatelier Principle
According to Le Chatelier's principle: What is going to happen to the color if you add more CuCl42- and why? The Kc is the equilibrium constant, the large the number the more product is favored. System 1: Cu²+(aq) + 4C1 (aq) = CuC142-(aq) Blue/Green Green/Yellow Kc or lc [CuCl2-] [Cu2+][C1-]4 O It will turn more Blue/Green and since you are adding extra chlorine ion O It will turn more Green/Yellow and since you are adding...

1. 1 Cu2+ (aq) + 4 Cl- (aq) ⇌ 1 [CuCl4]2–(aq) which reaction shifted the chemical equilibrium towards the forward direction? Which reaction shifted the chemical equilibrium towards the reverse direction? Explain your reasoning for both using Le Châtelier’s principle. 2. How does the temperature affect the copper(II) chloride equilibrium? Use Le Chatelier’s principle to explain whether the forward reaction is considered an exothermic or endothermic reaction.
