## Homework Statement

I have a chemistry teacher who discourages students from asking questions (long story, but he's just not a good teacher). We have an online textbook, which fails to explain a lot when it comes to formulas. One thing I want to understand is what the different letters and symbols in formulas and equations mean. Like when I see a "Q" or a "Δ" in a formula, I'd like to know what those things actually mean. I don't feel like memorizing a formula does me much good if I don't know exactly what those formulas are looking for, and feel I will gain a much better understanding of the material if I understood how different aspects of chemistry are formulated together in the different equations. In both chem I and II, all our teacher does is hand us formulas, then has us plug arbitrary numbers into those formulas, but doesn't explain what those numbers actually represent, so none of us really have any idea what we are actually calculating.

## Homework Equations

e-(Ea/8.314T)

ln [A] = –kt + ln [A]o

k=Ae^(-Ea/RT)

These are just a couple, but I don't know what the "e" "k" "t" "o in [A]o" "R" or "T" means.

## The Attempt at a Solution

Asking my teacher has proven futile, and I am in a small school so not sure who else would be good to ask. I have tried a web search to no avail and checked my local library and bookstore to no avail as well. I am open to any materials I could get my hands on that will help me to know what it is that I'm actually calculating so I may better understand what I am doing.
