### Re: Reducing power

So in a galvanic cell, whichever one is more positive, that means its more likely to be reduced and thus gains electrons (having e on the reactant side), and the more negative one is likely to be oxidized, and thus lose electrons (having e on the product side)? Yes, just make sure when you are look...

### Re: Units for K

zero order: rate = k first order: rate = k[A] second order: rate=k[A]^2 rate is always Molarity/second or Moles*Second^-1*Liters^-1 so when you have just rate = k for zero order.. Molarity/second needs to equal k, so k is Molarity/second (easy!) Now, when you have rate= k[A] for first order.. Molari...

### Re: Why is CH2Cl2 polar while CH4 is not?

CH4 is a C surrounded by all H's, so all of the H's pull the electrons from the carbon the same amount (i.e. nonpolar). In CH2Cl2, the Cl pulls much more on the Carbon's electrons (since it has higher electronegativity) than the Hydrogens, which sets up a dipole moment (i.e. polar).
