What is the percent yield of a reaction that produces 9.8 g of co when 25.0 g of fe304 reacts with excess carbon? fe304 + 4c â 3fe + 4co o 81.096 o o 39.296 43.2% 84.8% o l incorrect 0/1 point

Hey there!:

Balanced equation for this reaction is :

Fe₃O₄ + 4 C  > 3 Fe + 4 CO

1 mole of Fe₃O₄ gives 4 moles of CO

number of moles  = mass (g ) / molar mass ( g/mol)

Molar mass of Fe₃O₄ = 231.533 g/mol

Molar mass of CO = 28.01 g/mol

Moles of Fe₃O4 = 25.0 / 231.533 => 0.108 moles

Moles of CO =  4 x 0.108 => 0.432 moles

Mass of CO = 0.432 x 28.01

Mass of CO = 12.1 g

Percent yield =  ( actual yield / theoritical yield ) x 100

Percent yield =  ( 9.8 / 12.1  ) x 100 =

Percent yield =  0.8099 x 100 =

Percent yield = 80.99 %

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.
