5. Use Le Chatelier's principle to determine whether the equilibrium for the exothermic reaction below shifts...
Using Le Chatelier's Principle to predict the result of changing Nitrogen monoxide and ozone react to form nitrogen dioxide and oxygen, like this: The reaction is exothermic. Suppose a mixture of NO, O, NO2 and O2 has come to equilibrium in a closed reaction vessel. Predict what change, if any, the perturbations in the table below will cause in the composition of the mixture in the vessel. Also decide whether the equilibrium shifts to the right or left. shift in...
1) The reaction below is exothermic 2SO2 (g) + O2(g) ⇌ 2SO3(g) + heat Le Châtelier's Principle predicts that _______ will result in an increase in the number of moles of SO3 (g) in the reaction container. Which direction will the reaction shift: ? left or right A) increasing the volume of the container B) increasing the amount of SO2 C) removing some oxygen D) increasing the temperature E) decreasing the pressure 2) Consider the following reaction at equilibrium: 2SO2 (g) + O2 (g) ⇌ 2SO3 (g) + heat ΔH...
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:...
Based on Le Chatelier's Principle in which direction will the following reaction proceed if it is already at equilibrium given the following change in conditions. A(g) + 2B(aq) → 2C(g) ΔHrxn = 25 kJ The temperature is increased? The volume of the reaction vessel is increased? Water is added to the reaction? Solid B is added to the flask, which subsequently dissolves in the aqueous solution increasing the concentration of B? A catalyst is added? Helium is pumped into the...
Question 4 1 pts Le Chatelier's principle states that: Only exothermic reactions can reach chemical equilibrium. Only reactions in which a catalyst is present can reach chemical equilibrium. If a chemical equilibrium is disturbed, the system will try and reestablish equilibrium. If a chemical equilibrium is disturbed, the temperature of the system will always decrease.
34) According to Le Chatelier's Principle, if more reactant molecules is added to the system HNO, -H- + NO, A) equilibrium shifts to right to relieve the stress added to the system B) equilibrium shifts to the left to relieve the stress added to the system C) no change D) none of the above I

For each of the following equilibria, use Le Chatelier's principle to predict the direction of reaction when the volume is increased. Drag the appropriate chemical equations to their respective bins. chemical equations: 2H2(g)+ O2 (g) ⇌ 2H2O (g), C (s) + H2O (g) ⇌ CO (g) + H2 (g), 2Fe (s) + 3H2O (g) ⇌ Fe2O3 (s) + 3H2 (g) bins: Reaction will go toward products, Reaction will go toward reagents, Reaction will remain at equilibrium
