First Name: upon addition of the water, explain the reasoning for the shift in equilibrium. (Remember that liquids do not appear in the equilibrium expression, so you cannot say that it is increasing reactants making Qck. Water does not directly appear in QorK . 5. When the NO, was compressed to 15mL was the color more or less than twice as dark as the color at 30mL? Based on your answer to question 5, in which direction did the reaction shift with the reduced volume? Explain why this occurred. 6. 2 NO2 (g) = N,04 (g)Explanation / Answer
4.
Addition of water shifts the equilibrium due to the change in concentration of substances that involve in equilibrium though water does not appear in the equilibrium constant expression.
5.
Less than twice as dark as at 30 mL.
That is due to,
6.
Lechatlier principle decrease in volume or increase in pressure shifts the equilibrium towards less number of gaseous substances.
Hence in the given equilibrium, decrease in volume shifts the equilibrium towards products side.
