Indicating the location of a double bond

When naming an alkene, and indicating where the double bond is would it be right to put the location in the front of the name or in the middle? Let's say we have pentene and the double bond is located between the 2nd and 3rd carbon, would it be 2-pentene or pent-2-ence, or does it not matter?

1.5 Order Rxn?

What happens when the concentration rate doubles and the rate of the reaction of the rate multiplies by half of the square of the concentration? I have seen this before and I was wondering if this can exist or not.

Finding Ka

I was doing a practice midterm (2014) and I got stuck on #8 because it asked for Ka. Based on the answer, you're just supposed to take the square root of K. Is there also a relationship between K and Kb? Are there other relationships we are supposed to know?

Cell Diagrams

I noticed that in some of the half reactions do not have a element in the solid state, which is essential to draw a cell diagram. What do you do when this happens?

Pressure units

When doing heat and enthalpy related problems, I always find problems figuring out what units my pressure should be in. I've heard that they should be in bars, then I see atm often, too. So I'm just looking for a concrete, straightforward answer.
