Re: Isomer

There are 2 types of stereocenters, or when there are 4 different things around a Carbon. Depending on the atomic number of each, you can determine the order in which they are ranked and then determine if they are R/S. R is when the ranking is clockwise, S is when ranking is counterclockwise.

Re: Catalyst

Increasing temperature will increase the rate of reaction with catalysts, but up to a point. At around 40 degrees C, some enzymes will denature and no longer be able to catalyze.

Re: Reaction Order

There are a few ways to do this, but one way is to add the exponents of the concentration terms of the rate law.

Re: Intensive property

I had the same question. An intensive property is a property that doesn't depend on the physical quantity, like density. You could double a half reaction to balance the electrons, but since the standard reduction potential is constant it does not need to be double. Since 1 volt = 1 joule per coulomb...

Re: Entropy

You're right thinking that it's the randomness of a system. The result of entropy is randomness.

Re: open system

Not sure I 100% understand, but from what I have is: an open system is like a cup whereas a closed system is like a bottle. With bottles, we can't really get in there and add liquids or gas. With an open system like a graduated cylinder there can be both a transfer of mass and energy, since we can e...

Did you hear about the guy who's temperature got down to absolute zero? Don't worry, he's 0k.
