Answer:
Factors that can affect the rate the rates of chemical reactions in the body are temperature, substrate concentration and presence and absence of enzymes.
Explanation:
Rate of a reaction may be defined as the speed of the reaction or the rate at which reactants are converted into products.
Increase or decrease in the range of temperature can affect the rate of a chemical reactions of the body. With increase in the temperature the rate of a reaction increases as the effective collision between the substrate increases and then decreases.
Enzymes are the biocatalyst that can increase the rate of a chemical reaction. The absence of the enzymes decreases the rate of a reaction.
The increase in the concentration of substrate increases the rate of a chemical reaction of the body.
The effect the properties of water have on Earth’s surface and its systems include:
<h3>What is Erosion?</h3>
This is the process in which earthen materials are worn away and transferred from one part to another.
The absorption and retention properties of water also ensure that weathering takes place.
