When 100.0 g N 2 gas and 25.0 g H 2 gas are mixed at 350°C and a high pressure, they react to form 28.96 g NH 3 (ammonia) gas. Calculate the percent yield. Solution: We must calculate the theoretical yield of NH 3, and to do this, we must first discover whether N 2 or H 2 is the limiting reagent. For the …

WebAug 15, 2024 · The actual yield is stated in the problem, 6.1 metric tons. Thus, the percentage yield is % y i e l d = 6.1 t o n s 9.6 t o n s × 100 = 64 % Due to chemical equilibrium or the mass action law, the limiting reagent may not be completely consumed. Thus, a lower yield is expected in some cases. In chemistry, yield, also referred to as reaction yield, is a measure of the quantity of moles of a product formed in relation to the reactant consumed, obtained in a chemical reaction, usually expressed as a percentage. Yield is one of the primary factors that scientists must consider in organic and inorganic chemical synthesis processes. In chemical reaction engineering, "yield", "conversion" and "selectivity" are terms used to describe ratios of how much of a reactant was co…
