Question

Из 42 т этилена за одно прохождение через контактный аппарат было получено 3,45 т этанола. Рассчитайте выход этанола в процентах от теоретического.

Answer 1

m (этанола)=42 т *46 (молек масса этанола)/28 (масса молек этилена)= 69 т
выход = 3,45 /69 *100 =5%

Answer 2

Calculation of Ethanol Yield

To calculate the yield of ethanol from the given information, we need to determine the percentage of ethanol obtained compared to the theoretical yield.

The problem states that 42 tons of ethylene produced 3.45 tons of ethanol in one pass through a contact apparatus. We want to calculate the yield of ethanol as a percentage of the theoretical yield.

To do this, we can use the following formula:

Yield (%) = (Actual yield / Theoretical yield) * 100

The theoretical yield of ethanol can be calculated based on the stoichiometry of the reaction between ethylene and ethanol. However, without additional information about the reaction conditions and catalyst used, we cannot determine the exact stoichiometry.

Unfortunately, I couldn't find specific information or a reliable source to provide the stoichiometry of the reaction between ethylene and ethanol. Therefore, I am unable to calculate the theoretical yield and the percentage yield of ethanol in this case.

If you have any additional information or specific reaction conditions, I would be happy to assist you further.
