Find the rate expression for a reaction between propanone and iodine
The rate of reaction can be defined as the "increase in molar concentration of a product of a reaction per unit time" or the "decrease is molar concentration of a reactant per unit time." A quantitative way of showing this is through the rate expression. We can find this by performing a series of experiments: changing the concentration of one of the reactants whilst keeping the others constant.
A + B - C
The reaction above would have the rate expression
R (rate of reaction) = k [A] x [B] y
* The rate of reaction is measured in mol dm-3 s-1
* [A] [B] is the product of the concentrations of the reactants measured in mol dm-3
* x and y are the powers which the concentrations are raised to,
as well as the order of reactants A and B. They usually have values between 0 and 2
* k is the rate constant, with varying unites dependant upon the order of
