For the reduction of nitrobenzene, 5.6 liters of hydrogen were used, and 10 g of aniline were obtained. What is the yield of aniline from the theoretically possible?

1) Let’s compose the reaction equation:
C6H5NO2 + 3H2 = C6H5NH2 + 2H2O
2) Determine the amount of hydrogen:
n (H2) = 5.6 / 22.4 = 0.25 mol
3) Determine the yield of theoretical nitrobenzene
n (C6H5NH2) theory = 0.25 / 3 = 0.0833 mol
4) Determine the mass and yield of nitrobenzene:
m C6H5NH2theor = 0.0833 * 93 = 7.75 g
output = 7.75 / 10 = 0.775 * 100% = 77.5%
Answer: The product yield is 77.7%
