2 C6H5NO2 + 4 C6H14O4 = (c6h5n)2 + 4 C6H12O4 + 4 H2O how to calculate for the theoretical yield if your limiting reactant is 0.975 from nitrobenzene
Accepted Answer
The balanced chemical equation shows the reaction of nitrobenzene (C6H5NO2) with adipic acid (C6H14O4) to produce azobenzene ((C6H5N)2), succinic acid (C6H12O4), and water (H2O).
To calculate the theoretical yield, follow these steps:
1. Determine the molar mass of the limiting reactant (nitrobenzene): The molar mass of C6H5NO2 is approximately 123.11 g/mol.
2. Convert the mass of the limiting reactant to moles: Divide the given mass (0.975 g) by the molar mass to get the number of moles of nitrobenzene.
3. Use the stoichiometry of the balanced equation to find the moles of the desired product (azobenzene): The equation shows that 2 moles of nitrobenzene react to form 1 mole of azobenzene. Use this ratio to determine the moles of azobenzene produced.
4. Calculate the theoretical yield of azobenzene in grams: Multiply the moles of azobenzene by its molar mass (approximately 182.22 g/mol) to get the theoretical yield in grams.
Remember that the theoretical yield represents the maximum amount of product that can be formed under ideal conditions. The actual yield may be lower due to factors like incomplete reactions or loss of product during isolation and purification.
