Which of the following statements is true according to Le Châtelier’s principle? 1.Increasing the temperature of an exothermic reaction will decrease the product concentration 2.Increasing the temperature of an endothermic reaction will decrease the product concentration 3.Adding a catalyst shifts the reaction to the right 4.none of the above are true 5.Decreasing the volume of the container shifts the reaction to the side with more moles of gas

Consider the reaction in the gas phase: N2 + O2 + Br2   double arrows 2 NOBr Decreasing the volume of the container will __________.     shift the reaction to the left     increase the moles of reactants     decrease the moles of product     shift the reaction to the right

For questions 9-13. Consider the reaction 2NOCI(g) = 2NO(g) + C12(g). If this reaction is at equilibrium, what happens when the following changes occur? 9. NOCI(g) is added O shift to right shift to left no reaction O both shifts to right and left

Copper (I) chloride is not very soluble in water if solid copper(I) chloride is in equilibrium with a solution of copper(I) ions and chloride ions how will that equilibrium be affected by the addition of sodium cyanide? a) The equilibrium will not be affected by the addition of sodium cyanide b) The equilibrium will shift towards the product c) The equilibrium will shift towards the reactants

Two gaseous molecules react and produce two other gases molecules in an equilibrium reaction. What happens when the pressure is decreased? A  it shifts to the right B  more products form C It shifts to the left D Nothing happens

What le chatelier principle states? A. If a system is in equilibrium, it will remain in equilibrium in spite of changes in pressure or temperature  b. If a chemical reaction is at equilibrium and experienced a change in pressure, temperature, or concentration of products or reactants, the equilibrium shifts in the opposite direction to the offset the change

None

4. What does a bi-directional arrow tell you about a chemical reaction? The reaction happens only once The reaction happens more than once The reaction is able to reverse O The reaction is at equilibrium
