Generally, the energy required to initiate the reaction. Reactions that release energy (exothermic) can proceed faster than those that require energy to be added (usually in the form of heat energy).

The rate at which the chemical reactions in the body cells take place is known as the __________ rate.?
The rate of Metabolism, or metabolic rate.
Equilibrium is achieved when the and chemical reactions continue to take place at the same rate?
Equilibrium occurs when the forward and backward reactions happen at the same rate
Which best describes the role of enzymes in chemical reactions?
to increase the reaction rate
What controls the rate of chemical reaction in human body?
In the human body enzymes control the rates of chemical reactions. Enzymes speed up reactions by lowering the activation energy, or the amount of energy required for the reaction to occur.
How does increasing the temperature effect a chemical reaction?
Raising the temperature makes chemical reactions faster.
Do enzymes decrease the rate of chemical reactions?
No, they Increase the speed of chemical reactions
What is the rate of chemical reaction is?
The rate of chemical reactions is how long a chemical reaction takes to finish.
How particle collisions that affect the rate of chemical reactions?
When the number of particle collisions increase the rate of chemical reactions also increase.
What are the 5 factors that can affect the rate of chemical reactions?
5 factors that can affect the rate of chemical reactions are temperature, pressure, concentration, stirring, catalysts.
How the difference in the movement of atoms at two different temperatures affects the rate of most chemical reactions?
Generally at high temperature the rate of chemical reactions is greater.
Substance that increases rate of chemical reactions?
catalyst
What controls the rate of chemical reactions in cytoplasm?
mitochondria
What is a special protein that effect the rate of chemical reactions?
An enzyme
How does temperature aff ect the rate of chemical changes?
An increase in temperature increases the rate of most, but not all, chemical reactions.
The rate at which the chemical reactions in the body cells take place is known as the __________ rate.?
The rate of Metabolism, or metabolic rate.
Chemical reactions are at what when a reaction and its reverse happen at an equal rate?
Equillibrium
What is a protein that changes the rate of chemical reactions?
its called an enzyme
