I did a Chem Lab the other night where Data obtained from a spectrophotometer yeilded a coefficient to make us believe the experiment was a zero order reaction. However, the reaction is known to be first order. What are the possibilities of the experimental error? Why is the zero order correlation coefficient better than first order?
Under these conditions, the half-life of the reaction has been estimated to be 6.4 103 min. What would the half-life be if the initial concentration of NO were 13 ppm?
