Yes, coffee and tea are heated to speed things up.


What is the definition of catalysis?

Catalysis is the action to increase the reaction rate of a chemical reaction using substances called catalysts which are not transformed during this reaction.

no


What are the chemical substances which affect the rate which you grow?

Growth hormones affect the rate at which you grow.


Why substances might dissolve at different rates?

Substances dissolve at different rates because of differences in their molecular structure, size, and polarity. The solubility of a substance is influenced by the strength of the interactions between its particles and the solvent molecules. Additionally, factors such as temperature and pressure can also affect the rate at which a substance dissolves.

What are the chemicals substances that affect the rate at which we grow?

Growth hormones and Food.


Does purity effect dissolving rate and how?

Yes, the purity of a substance can affect its dissolving rate. Higher purity substances typically dissolve faster because there are fewer impurities or other substances present that might interfere with the dissolving process. Impurities can slow down the dissolving rate by creating barriers for the solvent to interact with the solute particles.


What methods would you use to dissolve a large crystal of salt known as rock salt in water Explain all the factors that affect the rate at which the salt will dissolve?

Broken the crystal in small parts; dissolution in water is easy.Factors which affect the rate of dissolution: temperature and stirring.


What factors affect the diffusion rate?

Diffusion refers to the process where substances from a highly concentrated area move to a place with a lower concentration. The three factors that affect the rate of diffusion are temperature, concentration gradient and the molecular weight of the substances.


When substrate concentration is much greater than Km the rate of catalysis is almost equal to?

the maximum catalytic rate (Vmax). At this point, all enzyme active sites are saturated with substrate and increasing the substrate concentration will not further increase the rate of catalysis.


What is the rule for dissolving?

When dissolving a solid into a liquid, the general rule is that "like dissolves like," meaning that substances with similar polarities will dissolve in each other. Additionally, increasing the temperature of the solvent usually increases the rate at which a solid dissolves. The size of the solute particles and the stirring of the solution can also affect the rate of dissolution.
