Initial Rate

When finding the initial rate or initial concentrations, is it possible that there'll be a case where you won't have constant initial concentrations to figure out each of the order of reactants? I think I came across this scenario once, so how would you approach the problem? This applies to problems where you are given a chart of the experiment #, the initial concentrations, and the initial rates in figuring out the k at any concentration-

i think they would have to give you one experiment where the concentration is held constant and then if both change in a different one you would first find the change from the one you already know and then find the change from the other change in concentration.

They should give something that remains constant because that is the method being employed.

The concentration of one substance has to be constant for you to determine the rate of the other substance whose concentration is changing at different times in the reaction.

They will only change the concentration of one substance from trial to trial

Where did you come across this problem? perhaps there was something else given that you looked over
