Question

Calculate the Theoretical Yield of your product, i.e. the mass you would expect to recover, assuming 100% conversion to product.(explain it too)

Pd/ H2 Ethyl cinnamate ethyl 3-phenylpropanoate Ammonium formate decomposes to give hydrogen, carbon dioxide and ammonia. The hydrogen then reduces ethyl cinnamate formula mol.-eq mmol name Ethyl Cinnamate Ammonium formate 10% Palladium on carbon Ethanol product amount 168 HL 472 mg 42 mg 16 mL 178.05 mg 1.00 176 .21 g/mol C11H1202 0.999 NH4HCO2 1.00 63.0559 g/mol 7.48 C2H5OH 06844 / C11H1402 1.00 178.23 g/mol 0.999 3). Since moles of ethyl cinnamate is less, it is the limiting reagent.

Explanation / Answer

answer: the decomposition of ammonium formate because it is the source of H2

1 mole of ethyl cinnamate required 1 mole of H2 according to given equation of conversion. Also, 1mole of ammonium formate decomposes to produces 1 mole of H2

since ethyl cinnamate is in 0.999 mmol and H2 is in 7.48 mmol indicates that ethyl cinnamate is the limiting agent ( the reactant that we consumed first) and decide the amount of product formed

so the amount of product formed = 0.999mmol

molar mass of product given 178.23g/mol , so the amount of product formed = 0.999 * 178.23 = 178.05 mg
