Re: Quiz 3 Winter 2017
When drawing reaction profiles for the Quiz will we be deducted points for writing the words "reactants", "intermediates" , "products"? Or do we have to write the actual molecules for reactants, intermediates, and products in order to get full credit?

Reaction Profile: How to Draw
Is there a way to draw a reaction profile without being explicitly told it is exergonic or endergonic? How do we determine the placement of reactants and products in the drawing (which is higher than the other)?
Example:
CH3Br + -OH --> CH3OH + Br- (from 4.35 ochem textbook)
Example:
CH3Br + -OH --> CH3OH + Br- (from 4.35 ochem textbook)

Approximation rule
What is the rule when trying to solve for K= [Products]/[Reactants] when there is an x to be solved for? In other words at what values of 10^? can we get rid of the x and solve?

Difference between K and Q
Because both K and Q are solved by [Products]/[Reactants], doesn't that mean that they will always be equal to each other? How will they be different numbers if the same equation is used to solve for them?

The equals(=) sign or greater than (>) sign? [ENDORSED]
With problems where we need to use the Heisenberg Uncertainty Equation why is it that the greater than equals to sign is changed to just an equals sign? And because that does happen do we not have to worry about the greater than sign flipping around when we divide by negative numbers for calculations?
