Recent Tutoring Session Reviews
"Today, the student and I reviewed material from our previous session. We devoted most of this session on significant figures and difficult dimensional analysis problems. She is doing well!"
"The student was introduced to chemical kinetics this week and we focused on the difference between rate of reaction and rate constant, which is a difficult concept because the rate constant is a proportionality constant between the reactant concentrations and the rate of reaction, but it's experimentally determined from concentration changes over time for a specific reaction. Therefore the rate constant is only constant for the specific reaction and takes into account intrinsic properties of the molecules involved. We also discussed what stoichiometry means about the change in concentration of reactants and products over time. We also went over her first exam which was focused on equilibrium, free energy changes, and reaction mechanisms. She was concerned with her performance but my assessment is her understanding of the topics is definitely there; the pace of her class is very fast and some of the equations are getting lost along the way. We went over each problem and she understood where she made her mistakes. Before her next test, we're going to create a one page outline of the important equations, terms, and concepts as the foundational knowledge she must memorize."
"Today we covered stoichiometry, definitions, converting between grams and moles, limiting reagents, and different types of problems that can be asked."
"In this session, we reviewed conversion between particles, moles, and mass. We then covered how to calculate empirical formulas given mass percentages. I think the student is really getting the hang of the conversions and just needs to be a little more confident in himself. During the session, he also completed part of an online quiz and did very well. The one issue he sometimes has is in remembering significant digits, but he knows to be aware of that now."
"In this session, we went over a few test problems and homework questions, including questions about converting from molecules to atoms and moles of ions; reaction coordinate diagrams/determining the direction of a reaction; and hydrogen, dipole-dipole, and induced dipole bonding. I hope the session was helpful, and it was nice meeting the student!"
"Last night we covered questions that the student had missed on her previous exam. We discussed the function of catalysts and activation energy, molecular orbitals, Lewis dot structure, and redox reactions. She did well on her last test and seems to be steadily improving."
