Degree: Medicinal and Biological Chemistry (Masters) - Edinburgh University
Hello I'm Lily and I'm a second year Chemist at the University of Edinburgh. Being passionate and enthusiastic about my subject means that I'm eager to help students conquer their difficulties with Chemistry to not only achieve the grades they desire but also enjoy learning the subject.
I'm avaliable for regular tutorials or just a one off to help with a particular area you're struggling with.
Sessions will be relaxed but productive, and will focus on helping you overcome any difficulties. Whilst studying for my A-levels/GCSEs I found past papers an effective way of achieving top grades and will try to incorporate these into our sessions. However I'm flexible in my teaching and will work to find the best method of learning to suit you.
If you have any questions feel free to book a 'Meet the Tutor session' or send me a 'Webmail.' I'm more than happy to help, and I look forward to meeting you.

When a reaction is feasible ΔG = 0. Rearrange the equation ΔG = ΔH - TΔS. So that when ΔG = 0, T = ΔH / ΔS.
Must convert ΔS from JK^-1mol^-1 to kJK^-1mol^-1 by dividing it by 1000.
Then plug in numbers given so T = (492.7 kJmol^-1) / (0.5426 kJK^-1mol^-1)
T = 908 K.see more
The melting/boiling point of a substance determines what state of matter it takes at a certain temperature.
In Cl2 there are covalent bonds between the atoms forming simple molecules. There are weak attractions between molecules of Cl2 meaning little energy is needed to break these forces of attraction and therefore Cl2 has a low boiling point.
NaCl on the other hand has strong electrostatic forces of attraction between the positvely charged Na ion and the negatively charged Cl ion. NaCl forms a giant ionic lattice that requires high amounts of energy to break and therefore has a high melting point.see more
