Limiting Reactant problems

Postby LeAirraBullingor2k » Thu Oct 03, 2019 10:53 pm

During lecture, Dr.Lavelle mentioned side reactions and how they will change the yield, will the lost product amount be given or is this just something. we estimate?

Are you talking about side reactions that are given, or side reactions that occur by chance? I would probably only utilize information that is given in the problem.

For problems asking to calculate the percent yield, the actual yield is usually provided in the prompt.

He basically mentioned this just to demonstrate an example of why the actual, experimental yield of a certain reaction may be lower than the theoretical, calculated yield. It's not something we calculate, just a possible justification for the discrepancy between the actual and theoretical yield. If anything, you can find the difference between theoretical and actual yield to see how much product was not produced and calculate the amount of product that was used up in another way.

If there's ever a need to know the amount of lost product, say to calculate the actual yield, they'll usually just give it to you. Most of the problems that I've seen related to this is just a) what's the percent yield (given actual and predicted yield), and then b) what are some reasons that the actual yield is less than the predicted yield.
