What we did today

1. Passed out the Reaction Rate investigation sheet

2. Started the Rate expressions and Rate constants Packet

To see what we did in the packet look on the moodle page for Rate expressions and rate constants packet

Important information for the Rate law

• When calculating the rate constant (k) you don't need to worry about the units
• When finding the rate of reaction do make sure your units are correct

Hw

1. Rate expressions and rate constants packet is due Monday

2. If you're going to be absent tomorrow make sure to check the blog for the data in lab due Monday

Wednesday February 3rd

We had a late arrival!!

What we did in class:

1. Went over the homework that was due yesterday

2. Took notes on Intermolecular Forces

3. Stared working on the Hw worksheets

Intermolecular Forces:

 There are three kinds

1. London Dispersion Forces
2. Dipole Dipole Force
3. Hydrogen bonding

The london dispersion method is also known as the Van Der Waals forces.  It includes Dipole between non-polar molecules to create a temporary attraction. Electrons can flow more in one direction than another, eventually temporary dipole.  The attraction is weak and short lived

The dipole dipole force is in between polar molecules. It when the + of one molecule attracts the - of another.  The attraction is a permanent one.

Hydrogen Bonding is like dipole on steroids.  It only happens when the H of one molecule attracts a F, O, or N of another molecule. 

HW:

1. Webassign due tonight by 11:59pm

2. Two IMF worksheets that we picked up at the beginning of class

3. Start the review packet!!! The test is this friday!!!!
