catalyst will generally reduce the activation energy
The presence of a catalyst affects the activation energy of a reaction by lowering the activation energy, helping the reaction go faster and making it so the reaction does not have to use as much energy to fulfill the products.
A catalyst affects a reaction by speeding it up. A catalyst, remember, does not participate as a reactant or product in the reaction. It facilitates the reaction by lowering its activation energy, making the reaction easier to happen.
A catalyst increases the reverse rate of the reaction
It is acting as a biological catalyst.
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.
yea
An outside agent that affects the speed or occurrence of a reaction is called a catalyst. Catalysts work by providing an alternative reaction pathway with lower activation energy, allowing the reaction to happen more quickly. They are not consumed in the reaction and can be used repeatedly.
In chemistry, they can work by adsorption (although there are other methods). This is when the catalyst attaches itself to the reactant particles and then weakens the bond between them, making it easier to react, thus 'lowering the activation energy' (the energy required for a reaction to start).
A chemical reaction is affected by temperature, pressure, presence of a catalyst , radiation and concentration. Hope I helped...
The nature of the reactants, the temperature (and pressure if gases are involved), and the presence of a catalyst.

In a typical chemical reaction, xA + yB --> zC, the rate can be expressed as: Rate = k (T) * [A]^x * [B]^y where k = Rate constant, a function of temperature [i] = molar concentration of reagent i So, chemical reaction rate is affected by temperature and reagent concentration. Thus any variable that affects temperature (e.g. pressure or volume in the case of gases) will also affect reaction rate. However, the rate constant k is also a function of activation energy, the energy required to drive the reagents to the point where the reaction must proceed to completion. This activation energy can be lowered by the presence of a catalyst. Thus the presence of a catalyst can also affect the reaction rate.
