Hello,

I am away again, and I do apologise.

I would like you to read the chapter on Entropy in your books (pg 173 to 175) and Free Energy (pg 176 to 177) and come to the next lesson with any questions you have about them.

We will then use our lesson time to tackle some problems in groups and to go through some common exercises. Entropy questions on their own are rare, so we will be doing questions on the combined topics.

Thanks
Ms Elias

Good morning,

I'm not going to be in school for our lessons today - I'm still coughing after 47 days and the GP has ordered rest.

Could you spend your lesson time making notes on Enthalpy Change of Solution (pg 170-172) in your books and ensure that you are able to:

1. define the enthalpy changes involved
2. construct cycles appropriately
3. use a cycle to calculate an unknown value

You should complete practice questions on pg 172  too.

You should also be able to explain why some solids have a slightly positive enthalpy change of solution, yet still dissolve (e.g. Q3)


If you have good results from the practical then you may choose to complete the questions from that worksheet instead - using your data to create enthalpy cycles and calculate the missing value.

I will be in on Thursday to look at Entropy ---- wooo...! :)
