What should your actual yield be compared to theortical?
Usually, the actual yield is lower than the theoretical yield because few reactions truly proceed to completion (i.e., aren't 100% efficient) or because not all of the product in a reaction is recovered. It's also possible for the actual yield to be more than the theoretical yield.
What is the formula for theoretical yield?
percent yield = actual yield / theoretical yield x 100%. percent yield = 15 g / 19 g x 100%. percent yield = 79%. Usually, you have to calculate the theoretical yield based on the balanced equation. In this equation, the reactant and the product have a 1:1 mole ratio, so if you know the amount of reactant, you know the theoretical yield is the same value in moles (not grams!).
Can an actual yield ever exceed a theoretical yield?
Of course, a “true” actual yield can NEVER be greater than the “true” theoretical yield in a reaction ( this is the answer to the last question you posed ). What I mean by a “true” theoretical yield is the theoretical yield wherein you have accounted ALL of the possible occurrences in your reaction.
Which formula can be used to calculate the actual yield?
? actual yield = [ (percent yield of the reaction) x (theoretical yield)]/100. So the right choice is: (Percent yield × theoretical yield) ÷ 100 . If it releases 5 tons a day and there are 7 days a take that answer and multiply by 5 percent (0.05) to find the amount released in one week. leave a comment if you need more .
