Many reactions are of the form:
dCA/dt = kCA
dCA/dt is the change in concentration of A with time
k is the reaction rate constantCA is the concentration of A
The rate constant often exhibits an Arrhenius relationship, so:
k=Ae^(-Ea/RT)
A is a pre-exponential term (constant)
Ea is the activation energy of the reaction (constant)
R is the universal gas constant (constant)
T is the temperature of the reaction
Therefore, as T increases, the value of the exponential term increases. This means that k will increase as T increases, and therefore dCA/dt will increases as T increases.
Hope that helps!

Why does Enzyme reaction rate decrease at 37 degrees?
Enzymes are catalysts for chemical reactions. All chemical reactions are affected by temperature. Higher temperatures make the reactions happen faster, and colder temperatures make them happen slower. At 37 degrees, just a little above freezing, many biological enzymes practically stop working.
How do enzymes in proteins facilitate chemical reactions within living organisms?
Enzymes in proteins speed up chemical reactions in living organisms by lowering the amount of energy needed for the reactions to occur. They do this by binding to specific molecules, called substrates, and helping them undergo chemical changes more efficiently. This allows biological processes to happen at a faster rate, enabling cells to function properly.
Without enzymes the chemical reactions in the body would?
Without enzymes, chemical reactions in the body would occur too slowly to sustain life. Enzymes act as catalysts, speeding up chemical reactions by lowering the activation energy needed for the reaction to occur. This allows essential processes such as metabolism, digestion, and DNA replication to happen at a much faster rate.
What controls the chemical reactions in a cell?
Enzymes are responsible for controlling the chemical reactions in a cell. These protein molecules catalyze specific biochemical reactions by lowering the activation energy required for the reaction to occur, allowing cells to efficiently carry out various metabolic processes.
How do enzymes, which are proteins, play a crucial role in catalyzing biochemical reactions within living organisms?
Enzymes, as proteins, speed up chemical reactions in living organisms by lowering the energy needed for the reactions to occur. They act as catalysts, allowing reactions to happen faster and more efficiently, ultimately enabling essential processes like digestion, metabolism, and cell growth to take place.
How do enzymes in your body make chemical reactions occur at a safe temperature?
Enzymes lower the activation energy needed for chemical reactions to occur, which helps them proceed at a faster rate and at a lower temperature. This allows reactions to happen efficiently within the body's normal temperature range, maintaining a safe environment for biochemical processes to take place.
How does increasing temperature increases rate reaction?
Temperature can increase and decrease the rate of reactions. Heat increases, while cold decreases the rate of reaction. With the help of enzymes.
How does heat speed up decomposition?
Decomposition involves chemical reactions and as a rough approximation, for many chemical reactions happening at around room temperature, the rate of reaction doubles for every 10°C rise in temperature. The reason for this is that for chemical reactions to happen, at the smallest scale, the individual chemical molecules have to bump into one another. As molecules warm up they begin to vibrate more and the chances of them bumping in to one another increases - the more bumps that happen, the faster the reactions go.
Why is chemical weathering faster in the tropics?
Chemical weathering is faster in the tropics due to higher temperatures and abundant rainfall, which accelerate the chemical reactions that break down minerals in rocks. The warm and wet conditions in the tropics provide an ideal environment for chemical processes to occur more quickly compared to drier or colder regions. Additionally, the presence of more vegetation in the tropics can introduce organic acids that further enhance chemical weathering.
What causes chemical reactions to happen?
It happen when it happen
Do chemical changes only happen at a heigh temperature?
No, chemical changes can occur at various temperatures depending on the specific reaction. While many chemical reactions do happen at higher temperatures to provide enough energy for the reaction to occur, there are also reactions that occur at lower temperatures. Temperature is just one factor that can influence the rate of a chemical reaction.
What happen during metabolism?
it is broken down to fuel chemical reactions & is created by chemical reactions.
What does cytoplasm do for the plant?
Were all the chemical reactions happen
What chemical reactions happen when a firework is lit?
combustion...
What controls chemical reaction in a cell?
In the cytoplasm, because that is where the chemical reactions happen.
Why is water important in the cells in your body explain with chemical reactions?
It speeds up the chemical reactions so most reactions wouldn't happen without water.
What change will most likely increase the rate of a chemical reaction?
Increasing the temperature of the reaction will most likely increase the rate of a chemical reaction. This is because higher temperatures provide more energy to the reactant molecules, allowing them to overcome the activation energy barrier and react more easily.
