A k value above 1 means. A. Equilibrium has been reached yet B. Equilibrium favors neither side C. Equilibrium favors reactants D. Equilibrium favors products

Which of the following is true for chemical equilibrium? I. Forward and reverse reaction rates are equalII. Equilibrium can be achieved from either directionIII. Reaction rates and therefore equilibrium is temperature-dependent. a I only b I and II only c II and III only d I, II and III

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

Use Le Châtelier’s Principle to explain the effect each of the following changes will have upon the system—will the equilibrium shift toward the product or reactant side? Why? N2(g) + 3 H2(g)  ↔ 2 NH3(g) + heat a. If more hydrogen is added to the system the equilibrium will shift to the..... (pick one and explain)i. Right ii. Left iii. Remains unchanged b. If ammonia is removed from the system the equilibrium will shift to the..... (pick one and explain)i. Right ii. Left iii. Remains unchanged c. If nitrogen is removed from the system the equilibrium will shift to the..... (pick one and explain)

20. Equilibrium is the state in which a. The rate of the forward reaction is greater than the reverse reaction. b. The rate of the reverse reaction is greater than the forward reaction. c. The rate of the forward reaction and reverse reaction are equal. 21. What is a catalyst?

14. At equilibrium, the concentration of the reactants and the products in a reaction a. are equal b. remain constant with time c. change with time d. more than one choice is correct

If the equilibrium constant, K, is greater than 1 which of the following is true? Select one: a. There are more products than reactants. b. There are more reactants than products. O c. We have all reactants and zero products. O d. The number of reactants equals the number of products.

f the value of Q is greater than K for an equilibrium reaction then   a. a catalyst is necessary to achieve equilibrium.   b. the reaction will proceed to the right until equilibrium is established.   c. the reaction will proceed to the left until equilibrium is extablished.   d. the reaction will go left or right depending on the reaction stoichiometry.   e. Both (a) and (d) are correct.
