You'd better look more deeply, because it ain't that simple. The overall reaction is actually a sequence of several reactions, most of them binary. That is, two reactants produce a third (product) material. But that third is an intermediate - it becomes the input reactant for the next step in the sequence. And somewhere along the sequence we find that one of the reactions is the slowest of them all. It becomes the "Rate-Determining Step", and the rates of all the other preceeding and following reactions don't matter. It is the rate constant and / or the Activation Energy of this one step you need.
Now, even the Activation Energy alone does not help. You also need the temperature and an equation known to link those two to the rate constant, like Eyring's Equation, and the values for its other (fixed) parameters. Then, having found the rate constant, you look at the rate equation and find that, to get to the actual rate, you need the concentrations of the two input reactants and of the product. These are NOT the same as the inputs of original raw materials, etc - the reaction is in the middle of a sequence!
Ooops! My age is showing. You're trying to get answers fast on the internet, and I'm telling you to check out books!
It comes down to knowing what the original questions were. Were you asked to find the rate constants and Activation Energies (or Enthalpies and Entropies)? Were you asked how long it would take to convert x grams of glycerol to nitroglycerine? Be clear what the questions are. Then try looking BOTH in textbooks on Physical Chemistry and on Organic Chemistry. The Phys guys will talk about reaction kinetics, etc. But the specific reaction you talk about is often considered a simple Organic Chem one. Then look more at Industrial Chem and Engineering - you might find it in a text on chemical plant design.
