In this approach, you analyze initial rate data by fixing the concentration of all but one species, say X. Next, the rate law equation is linearized through a logarithmic transformation and a least-squares analysis is used to obtain a and its standard devaition. The process is repeated by keeping (X) constant and varying [Y] to obtain b and its standard deviation. Finally, using a and b, the average value of k and its standard deviation are deduced. a +/- b = +/- || +/- Reaction order k +/-
