Kyle Paulk SI CHEM 1201 1. is the maximum quantity of product that can be obtained from a chemical reaction if everything in the lab goes according to plan and works perfectly; only achieved as a calculation on paper; calculate this using the stoichiometric ratio between the product and the limiting reagent 2. is the quantity of product actually obtained; no one is perfect so this is generally less than the theoretical (for problems involving percent yield, this will be given with some kind of clue: 12g of CO2 was obtained ) 3. is the ratio of the actual to the theoretical yield expressed in percent A reaction can theoretically produce 7.65g of a product, but only 5.76g have been obtained in the lab. What is the percent yield? A reaction is 33.3% productive. What must have been the calculated maximum yield if only 25.1g of the product were obtained? General Stoichiometry Problems 4FeCr 2 O 7 (s) + 8 K 2 CO 3 (s) +O 2 (g) 2Fe 2 O 3 (s) +8 K 2 CrO 4 (s) + 8 CO 2 (g) How many moles of O 2 are required to produce 352 g of CO 2 ?
