Abstract
The rate of a chemical reaction may depend upon reactant concentrations, temperature, and the presence of catalysts. The results from the experiment show the orders are k [I]0[H2O2] and overall order is 1 and the reaction rate is 0.0500/Δt. The rate constant is 1.04 x 10-2 s-1.
Introduction
The rate of a chemical reaction may depend upon reactant concentrations, temperature, and the presence of catalysts. At a fixed temperature, the rate of a reaction may be mathematically described by a rate law. In this experiment the rate law for the chemical reaction, 2I + H2O2  I2 + 2H2O. The reaction rate must be measured and the values of the constant (k) and order (p and q) for the rate law k [I]p [H2O2] q can be calculated.
