Hello everyone and thanks for your help. I have the following problem, I have ten lists of numbers:p1,p2,p3....... p1={{41., 4.27541}, {41., 4.27576}, {41., 4.27518}, {41., 4.27506},.......} p2=.........etc the lists of numbers are data where the first term is time and second a concentration: {time,concentration} now I have a function where the concentration is a function of the time and 2 other parameters: c=f(kr, kc, time). How to fit the lists of data {time,c} with c=f(time, kc,kr) by finding the couple {kr,kc} for each list? In other words I'd like to find 10 couples of {kr,kc} fitting the equation c=f(time, kc,kr) Thanks again all of you.
