Spent the day editing some of the questions I have already done, I was unsure as to what I should do for some of the questions however.

Completed two more kinetics questions that work very well, have also almost completed a third to do with half lives, sadly though I got kicked out of 3S and the computers in the library seem to be struggling with what I need, thankfully though I did complete my 3 hours before being removed.

Finished a question on the Arrhenius equation, had multiple difficulties with it so sadly couldnt complete as much as i wanted to today.

Still ive set up the ground work for the next question in my kinetics category and this one should be a lot easier to put together.

Finished a chemical kinetics question on zeroth order reactions and another simple pH question involving conversion from pOH to pH.

Had to do my work on Monday instead of Wednesday sadly as I have had another very busy Wednesday.

I have also begun notes on a kinetics question involving the Arrhenius equation.

Came in at 9am and worked till 12 as I have a very busy evening. Completed a differential question, another pH question and a am half way through a zeroth order reaction question.

Nearly finished another integration equation, unfortunately I was having some troubles with it but it is nearly done now. All i need to do is set the answer to be to the nearest whole number and it will be ready for upload.

Next week i will looks at pH questions and more rate equations this time involving zeroth order rate equations and the Arrhenius law

Started at 12.30 so am leaving at 3.30

Uploaded the question I worked on last week having repaired any mistakes that i made. Uploaded a second differential question which needs to be solved a different way and involving insects.

I am now working on another differential looking at the rate of decay of bacteria with an applied pathogen.

Uploaded a completed question involving solving differentials using caffeine as an example.

Came up with another real life example of solving differentials by using rate laws and solving a first order rate law applicable to an SN1 reaction of (CH3)3C-Br + H2O.

Enjoying doing this question so far, its not too complicated and is very very important to chemists, I am glad for the refresher myself. But the solution is quite long and hence writing the feedback is taking a while. However it is nearly done and just needs brushing up for uploading next week.

After this I will look at doing something similar for a second order reaction.

Gave up on the integration by parts second question. It was taking way too long and wasting a lot of time. Uploaded my first one that was successful however and I have now almost completed a 'solving differential' question thanks to the example Hazel gave me. I am annoyed at how much time ive wasted. I think I am going to try sticking with slightly easier questions from here on.
