What is "b" (rates of forward and reverse reactions are equal)
200

What is to the right (forward)
200
A + B <----> C Reaction is exothermic How will removing heat shift the reaction?
What is shift to the right to replenish lost heat
200
A + B <----> C This reaction is exothermic. How could you shift this reaction to the right?
What is add A or B OR remove C OR decrease temp OR increase pressure
200

What is d. all of the above
300
What is the shift? K = Q
What is : no shift (@ equilibrium)
300
A (g) + 2B (g) <----> C (g) How will increasing pressure shift the reaction?
What is shift to the right to reduce pressure (reduces # moles of gas particles)
300

Kp is used to write an equilibrium expression in terms of _______.
What is gas pressure
400
Q > K
What is to the left (reverse) because more than required products for equilibrium are present and need to be used up to attain equilibrium.
400
A <----> B Endothermic reaction How will heating the substance affect the reaction?
What is shift to the right to remove "excess" heat from reactant side of arrow.

Name that artist
Who is Whitney Houston
500
When using Kp, the unit must be in _____
What is atm
500
How does the reaction shift? Q < K
What is to the right (forward) because the concentration of products is too small and more need to be formed to attain equilibrium.
500
A + B <----> C How will removing "A" shift the reaction?
What is shift to the left to replace the lost "A."
