Degree: Chemistry (Masters) - Manchester University
I'm a final year undergraduate Chemistry student at the University of Manchester. I have a strong background in science from my A-levels, and have recently spent a year working within Chemical Industry; meaning I know what it takes to apply an academic subject to real life and can bring what you may see as 'boring revision' to life!
I am really passionate about teaching Chemistry in new and interesting ways, honestly, it CAN be fun! I have had a lot of experience working in schools mentoring students about University applications and have had a lot of interview experience which I can reflect on to give some mock interview practice.
I generally have a good overview of Chemistry, and there's a surprising amount of Maths in what I do on a day to day basis! Anything I don't have the answer to right away, I will definitely be able to work it out and get back to you; I love a good challenge!
In my sessions, I would usually start off with a short discussion of what you understand, and what you feel like you need to work on. Moving on from this, I'll usually set up a few activities to help you see the subject matter in a different, more interesting way. I feel that discussing the topics is a great start to gain confidence in answering questions. Brainstorming answers to exam questions together is something else which I feel is a really effective way to learn, and I will often generate my own exam-type questions, and make model answers, especially for the more mathematical topics- practice of these types of questions is key to success, you can never do too many!
I have always practiced exam questions, and read around the subject- meaning that I have a huge bank of knowledge around many A-level and GCSE topics which I would love to share!

deltaG= Gibbs free energy
deltaG=deltaH - TdeltaS
If deltaH= 150 kJ/mol and deltaS=2.1 J/mol we must first convert the deltaS into kJ/mol, this is done by multiplying by 10-3 .
So deltaS= 2.1 x 10-3 kJ/mol. If the reaction is done at 25 degrees celcius, we must convert it to Kelvin, by adding 273. This gives 298 K.
So the value of deltaG can be worked out:
deltaG= (150 kJ/mol) - (298) x( 2.1x 10-3)
deltaG= 149. 4 kJ/mol
