Document Summary
Chemical kinetics understanding how quickly chemical reactions take place. Rate of chemical reaction is how the rate of concentration changes over time not how many moles per second it"s how many moles/l per second. Rate of reaction = change in concentration/change in time divided by stoichiometric coefficient and account for the sign (rate of reagent change is negative and rate of product change is positive) Think of the rate of reaction as a mole of reaction. Rate or reaction is a number with units of mol/l/s m/s. How quickly a reaction is happening at any particular instant. Tangent to the curves give the instantaneous rate at that time. If reaction is making/consuming gas products relationship between pressure and concentration use pv=nrt. Can also use spectrophotometry measure how much light is going through a sample indicates the number of absorbers . Filter paper chromatography separate different products and measure what"s going on with each of them separately.
