Question

В организме человека реакция окисления этанола протекает по уравнению: C2H5OH + O2 → CH3COOH + H2O. Определить, как изменится скорость реакции, если увеличить концентрацию этанола и кислорода в 5 раз.

Answer 1

5C2H5OH+5O2=5CH3COOH+5H2O

Answer 2

Reaction of Ethanol Oxidation in the Human Body

In the human body, the reaction of ethanol oxidation occurs through the following equation:

C2H5OH + O2 → CH3COOH + H2O

This reaction is catalyzed by enzymes called alcohol dehydrogenases and aldehyde dehydrogenases, which are present in the liver and other tissues. The process of ethanol oxidation is an important step in the metabolism of alcohol in the body.

Effect of Increasing Ethanol and Oxygen Concentrations on Reaction Rate

Increasing the concentration of ethanol and oxygen in a reaction generally leads to an increase in the reaction rate. This is because the rate of a chemical reaction is directly proportional to the concentration of the reactants.

According to the collision theory, for a reaction to occur, the reactant molecules must collide with sufficient energy and in the correct orientation. Increasing the concentration of reactants increases the frequency of collisions, thereby increasing the likelihood of successful collisions and the reaction rate.

Therefore, if the concentrations of ethanol and oxygen are increased by 5 times, it is expected that the reaction rate will also increase. The higher concentration of reactants will result in more frequent collisions, leading to a faster reaction.
