WebThe amount of a product that is formed when the limiting reactant is fully consumed in a reaction is known as the theoretical yield. In the case of our hot dog example, we … WebCalculatethe theoretical yield of TiCl4 (assuming complete reaction)and its percentage yield. The text explains that one reason why the actual yield for a reaction may be less than the theoretical yield is side reactions. Suggest some other reasons why the percent yield for a reaction might not be 100%.
WebTo make this possible, chemists consider two factors: 1. The percentage yield of a reaction. A measure of how effective an industrial process is in producing a product. 2. The atom economy of a reaction. A measure of how efficiently a reaction uses the atoms of reactant supplied. Percentage Yield
