H2O(l) --> H2O(g) at zero degrees C and 1000 atm. Is this reaction spontaneous? 

No, and you won't observe it. 

100
How does one calculate the equilibrium constant?
[product]^coefficient*[product]^coefficient [reactant]^coefficient*[reactant]^coefficient
100
What does Le Chatelier's principle state?
That a system at equilibrium will resist any stress put upon it.
100
Why does the rate of reaction change with an increase in temperature.
Particles impact more frequently and with more force.

A mother saw her daughter 30m away about 50m from a polar bear if the polar bear can travel at 18m/s and the mother can travel at 7m/s, will she get to her daughter before the bear if the she has to travel an additional 5 metres around a bunch of penguins?
Yes, Polar bears exist in the northern hemisphere and penguins in the south, so this situation must be taking place in a zoo.

What are two equations for calculating Gibbs free energy?

DG= DH -TDS or DG = -RTlnk

Write the equilibrium constant equation for electrolysis of water into H2 and O2.
[H2]^2[O2] [H2O]^2

If you wanted to change the K value of a system at equilibrium what must you change?
Temperature.

A solution that has dissolved as much solute as it can and then has had the temperature reduced is called what?
Supersaturated.

The rich need it, the poor have it, and if you eat it you will die. What is it?
Nothing.

Dante aligheri pictured 9 circles of hell with the innermost circle housing the worst of offenders from society. Is going from the outrmost circle endothermic or exothermic? Justify your answer

answers may vary.

What is the equation for K for displacement reaction Zn + 2AgCl(aq) = 2Ag + ZnCl2(aq)
[ZnCl] [AgCl]^2

Describe what happens to the chemical system A + B = C + D + 57kJ when the temperature is increased.
Reactants are favoured because the reverse reaction is endothermic which is sped up by the increase in temperature.
300
Why doesn't a catalyst effect the K value?
It speeds up both the forward and reverse reaction.

What is the best college basketball team in the USA? 100 more points if you can name a player on the team. 

Gonzaga, chet Holmgren or Drew Timme are the best known players.

What is the third law of thermodynamics? How can you prove this law is true?  200 points for each. 

at 0 K, the entropy of a pure crystal is zero. This law was determined from the chilling of various ideal gasses to show that their volume at 0 K is zero

Ca3(PO4)2(s) = 3Ca(aq) + 2PO4(aq)
[Ca]^3*[PO4]^2 1

For the reaction X2(g) + 3Y2(g) = 2XY3(g) at equilibrium; what would be the result of decreasing the amount of X2?
[XY3]^2 Decreases [X2] decreases*[Y2]^3 increases.

If two reactant particle impact each other and do not form the activated complex, give two reasons why they may have a successful impact in the future.
Better geometry of impact. Better vector of impact.
400
Why are manhole covers round?
Easier to roll to transport, the diameter is equal so it can not fall down the hole.

If NaCl dissolves in water and the temperature goes from 21.55 C to 10.55 C, what is the sign for DG? How do you know this?

negative because it was spontaneous.

HCN= 0.25M H+=1.5*10^-4M CN-=2.3*10^-3M what is the Q value? Is it at equilibrium if K=6.2*10^-10
1.4*10^-6 K is not equal to Q
500
For the reaction X2(g) + 3Y2(g) = 2XY3(g) at equilibrium; what would be the result of decreasing the pressure?
Reactants favoured. Decrease in pressure favours increase in gas particles to equalize gas pressure.
500
What is the difference between a catalyst and a reaction intermediate?
Catalysts exist at the begining and end of a reaction but are in other compounds during the mechanism of reaction, whereas intermediates are apart of neither the reactants or products but are present during the mechanism of reaction.

What is the biggest organism on earth?

a fungus in Oregon. but I'll accept either an aspen grove or a giant sequoia as well.
