How does the rate of a heterophase reaction depend on the contact surface of the two phases?
How does the rate of a heterophase reaction depend on the contact surface of the two phases? How does the size of the contact surface of the two phases depend on the degree of grinding of the solid phase? Which zinc sample, taken as a granule or taken as a powder, will react with hydrochloric acid at a faster rate?
The larger the contact area of the reacting substances, the higher the rate of the heterophase reaction. The greater the degree of grinding of the solid phase, the higher the amount of contact between the two phases.
A zinc sample taken in the form of a powder will more likely interact with hydrochloric acid than zinc in the form of a granule, because the powder has a higher degree of grinding, which means that the contact between the two phases and the reaction rate are higher.
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
