Initial Rate

[Sofia Ban]

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-

[Kate Osborne 1H]

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.

[Brittney Hun 2C]

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

[Jainam Shah 4I]

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.

[Chris Charton 1B]

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
