List 3 factors that can speed up the rate of chemical reactions

zysi [14]

Answer:

Temperature
Greater Surface Area
Catalysts

Explanation:

Temperature

An increase in temperature typically increases the rate of reaction. An increase in temperature will raise the average kinetic energy of the reactant molecules. Therefore, a greater proportion of molecules will have the minimum energy necessary for an effective collision (Figure. 17.5 “Temperature and Reaction Rate”).

Greater Surface Area

The rate of a chemical reaction can be raised by increasing the surface area of a solid reactant. ... more particles are exposed to the other reactant. there are more collisions. the rate of reaction increases.

Catalysts

A catalyst is a substance that can be added to a reaction to increase the reaction rate without getting consumed in the process. Catalysts typically speed up a reaction by reducing the activation energy or changing the reaction mechanism.

Plant hormonal regulation differs from animal hormonal regulation in that

Over [174]

Answer:

Plant hormonal regulation differs from animal hormonal regulation in that there are no dedicated hormone-producing organs in plants as there are in animals.

Explanation:

<em>Plant hormones control different functions in plants such as growth and development.</em> These hromones are signal molecules that affect gene expression and transcription levels. What diferentiates them from animals is that in plants there are no dedicated hormone producing organs. For example, that plants and insects produce their hormones differently.
