reaction rates and concentration (research paper) By katie prestage what are reaction rates? The rate of reaction is the speed in which a reaction takes place. This can be measured by the rate in which a reactant is used up‚ or the rate a product is created. If a reaction has a low rate‚ it means that the particles are combining at a slow speed. If the rate is high‚ it means that the particles are coming together at a fast speed. For example‚ the rusting of iron through oxidation has a slow

a stroke. In this‚ 610‚000 are first and new and 185‚000 are recurrent strokes. Nearly 75% of all strokes occur in people above the age of 65.

Internal Rate of Return In investment decision analysis you may need to calculate internal rate of return. “Internal rate of return (IRR) is the discount rate that gives the project a zero NPV” (McLaney‚ 2006).
