Question

2.(4 балла) Перечислите факторы, влияющие на скорость химической реакции: 2H2 + 02 - 2H2O - Q a) природа реагирующих веществ б) концентрация реагирующих веществ в) изменение давления г) присутствие ингибитора д) повышение температуры е) присутствие катализатора ​

Answer 1

Ответ:

бвд

Объяснение:

т.к. водород и кислород - это газы, значит пойдут их концентрация, изменение давления этих газов и повышение температуры. Ингибитор - это противоположность катализаторов. Они, как и природа реагирующих веществ действуют на Металлы и растворы.

Answer 2

Factors Affecting the Rate of Chemical Reactions

Several factors can influence the rate of a chemical reaction. Here are the factors that can affect the speed of the reaction between 2H2 and O2 to form 2H2O:

a) Nature of the Reacting Substances: The nature of the substances involved in the reaction can impact the reaction rate. Different substances have different reactivity levels, which can affect how quickly the reaction occurs. For example, some substances may have a higher activation energy, making the reaction slower.

b) Concentration of the Reacting Substances: The concentration of the reactants can significantly affect the reaction rate. Increasing the concentration of the reactants generally leads to a faster reaction. This is because a higher concentration means more reactant particles are present, increasing the chances of successful collisions and reaction.

c) Pressure Changes: In the case of gases, changes in pressure can influence the reaction rate. Increasing the pressure can lead to a faster reaction, as it increases the number of collisions between gas molecules, resulting in more successful reactions.

d) Presence of Inhibitors: Inhibitors are substances that can slow down or prevent a chemical reaction. They work by interfering with the reaction mechanism, reducing the rate of reaction. The presence of inhibitors can significantly impact the speed of the reaction.

e) Temperature Increase: Increasing the temperature generally increases the reaction rate. This is because higher temperatures provide more kinetic energy to the reactant particles, leading to more frequent and energetic collisions. As a result, the reaction occurs faster.

f) Presence of Catalysts: Catalysts are substances that can speed up a chemical reaction without being consumed in the process. They work by providing an alternative reaction pathway with lower activation energy. Catalysts can significantly enhance the reaction rate by increasing the frequency of successful collisions.

Please note that the information provided above is based on general knowledge about chemical reactions. For more specific information about the reaction between 2H2 and O2 to form 2H2O, it is recommended to refer to reliable chemistry textbooks or academic sources.
