Catalyzed reactions have a lower activation energy (rate-limiting free energy of activation) than the corresponding uncatalyzed reaction, resulting in a higher reaction rate at the same temperature
Catalysts work by providing an (alternative) mechanism involving a different transition state and lower activation energy. Consequently, more molecular collisions have the energy needed to reach the transition state. Hence, catalysts can enable reactions that would otherwise be blocked or slowed by a kinetic barrier. The catalyst may increase reaction rate or selectivity, or enable the reaction at lower temperatures. This effect can be illustrated with a Boltzmann distribution and energy profile diagram.
in bio chemical reaction enzymes are catalyst and do same work as normal catalyst.
What else can I help you with?
Is a catalyst generally required in biochemical reactions?
No, not all biochemical reactions require a catalyst. However, catalysts can help accelerate the rate of biochemical reactions by lowering the activation energy required for the reaction to proceed.
Do catalysts affect temperature?
A catalyst affects the speed of a chemical reaction. If the chemical reaction gives off heat, the reaction may affect the temperature, but the catalyst by itself doesn't affect the temperature.
Is sugar a good catalyst?
Sugar is not a catalyst because it does not participate in the chemical reaction by lowering the activation energy or being consumed in the reaction. It is often used as a reactant or substrate in various biochemical processes instead of a catalyst.
What type of catalysts effect biochemical reactions?
Enzymes are the most common type of catalyst that affect biochemical reactions. They are proteins that facilitate specific chemical reactions in living organisms, speeding up the reaction without being consumed in the process.
How does the presence of a catalyst affect the enthalpy change of a reaction?
The presence of a catalyst affect the enthalpy change of a reaction is that catalysts do not alter the enthalpy change of a reaction. Catalysts only change the activation energy which starts the reaction.
What chemical reaction is an enzyme?
The enzyme is a biochemical catalyst.
What type of catalyst affects biochemical reaction?
Enzymes

How do catalyst and inhibtors affect reaction rate?
A catalyst speeds up the reaction and lowers the amount of heat needed.
What type of catalysts effect biochemical reactions?
Enzymes are the most common type of catalyst that affect biochemical reactions. They are proteins that facilitate specific chemical reactions in living organisms, speeding up the reaction without being consumed in the process.
How does a catalyst affect the speed of a reaction?
A catalyst enables more particles to reach the activation energy and to take part in the reaction. Therefore the speed of the reaction increases.
How does the presence of a catalyst affect the enthalpy change of a reaction?
The presence of a catalyst affect the enthalpy change of a reaction is that catalysts do not alter the enthalpy change of a reaction. Catalysts only change the activation energy which starts the reaction.
Does a catalyst affect a reaction activation energy?
yes. lowers it.
Why does catalyst affect reaction speed?
The activation energy is reduced.
Assuming that the reaction is at equilibrium what effect does the addition of a catalyst have on the equilibruim?
a catalyst lowers the activation energy for both the forward and reverse reaction. however, it does not change the potential energy of the reactants or products. it also does not affect the heat of reaction (delta h)
