Document Summary
You cannot control or catalyze the molecules for perfect orientation. Study of rate of chemical reactions and how fast they proceed. Equal to the change in concentration divided by change in time. When determining change in anything, always subtract the initial value from the final value. Useful because not all reactants are converted to product at once. Gives you individual steps of how a reaction proceeds. Must always multiply by -1 to get a positive rate for decomposition. Molecules must collide with enough energy to break and form bonds in perfect. Rate is equal to the rate constant multiplied by the concentration of each reactant. Rate of a chemical reaction over a given period of time. Rate of chemical reaction at a specific moment in time. Must draw tangent line in order to find this rate. Point on graph where the reaction is complete. Time is greater than 0 at this point.
