This week we reviewed and compared entropy, heat capacity and exothermic/endothermic reactions. We also did a lab finding the pH's of a variety of household substances.
Homework due 4/25 is to:
Complete the enclosed .pdf
Using the simulation at this link follow the directions below and answer the questions.
Pull the red handle what do you see happen?
Now launch the C ball, what do you see happen?
Explain difference
Click on Many Collisions
Pump in some A
Pump in some BC
Note reaction at the bottom
Increase heat, what happens to total average energy as you do
Watch the current amounts of reactant and product. What is happening with them now?
Is this endothermic or exothermic
Is entropy increasing or decreasing?
Would this reaction take place spontaneously?
Hit Reset all
Now change reaction to the bottom A + BC
Pump in some molecules of A and BC
What happens?
Is this endothermic or exothermic
What happens to entropy?
Would this reaction take place spontaneously?
Hit Reset all
Change reaction to the second A + Bc
Pump in some molecules of A and BC
What happens?
Do you have to do anything to get the reaction to take place?
Is this endothermic or exothermic
What happens to entropy?
Would this reaction take place spontaneously?
Hit reset all
Change reaction to the 3rd A+BC
Pump in some molecules of A and BC
What happens?
Do you have to do anything to get the reaction to take place?
Is this endothermic or exothermic
What happens to entropy?
Would this reaction take place spontaneously?
