For TLC plate separation, why do we use Rf values instead of distance measurements (e.g. the spot travelled 5 cm from the starting line)? What would happen if we compared solvent systems using distances rather than Rf values?
why can the Rf value be used to distinguish the substances from one another? and Why...
why can the Rf value be used to distinguish the substances from one another? and Why is anRf value rather than the distance the spot moved used to help identify a substance by TLC?

Cost equations are often used to obtain factor demands. How can factor demands be obtained from a cost equation? Why would one obtain factor demands this way instead of obtaining them from the profit maximization problem directly?
