What greatly influences the rate and direction of reactions?
Factors such as temperature, concentration of reactants, presence of a catalyst, and the activation energy required can greatly influence the rate and direction of chemical reactions. Temperature affects the kinetic energy of molecules, concentration affects collision frequency, catalysts lower activation energy, and the nature of reactants and products determines the direction of the reaction.
What factors affect the rate of catalase catalyzed reactions?
If your question is "What affects catalyst performance?" (i.e. what stops them from working) then there are 2 main things: Atoms permanently bonded to the surface, blocking it, and so that stops other reactant molecules from sticking to it (catalyst poisoning) Catalyst sintering: This can be seen on high temperature solid metal catalysts, where there is a gradual loss of surface area for reactant molecules to stick to as a result of the individual catalyst surface atoms combining together (due to the heat) to make one big blob of lower surface area
What affects the speed of reaction in a cell?
The speed of reaction in a cell can be affected by factors such as enzyme concentration, substrate concentration, temperature, and pH levels. Enzymes are biological catalysts that facilitate chemical reactions, so their availability and activity can significantly influence the speed of reactions within a cell. Additionally, the concentration of substrates and the environmental conditions can also impact reaction rates.
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.
What physical factors control the rate of chemical reactions?
Physical factors that control the rate of chemical reactions include temperature, pressure, concentration of reactants, and surface area of the reactants. Temperature influences the kinetic energy of particles, pressure affects the collision frequency of molecules, concentration determines the number of reactive collisions, and surface area determines the contact area between reactants.
What are the factors that affects a chemical formula?
A chemical reaction is affected by temperature, pressure, presence of a catalyst , radiation and concentration. Hope I helped...

How would the equilibrium concentration of H2O be affected by adding a catalyst to the mixture?
Adding a catalyst to the mixture would not affect the equilibrium concentration of H2O. A catalyst speeds up the rate of the forward and reverse reactions equally, without changing the position of the equilibrium. This means that the equilibrium concentration of H2O would not be affected by the presence of a catalyst.
What type of catalyst affects biochemical reaction?
Enzymes

What affects the rates of chemical reactions?
The physical states of the reactants (gases, plasmas, liquids, solids), the temperature in which the reaction takes place and the pressure under which the reaction takes place are all factors that affect the rate of a chemical reaction. Factors such as humidity, concentration and surface surface areacan also affect the reaction. The presence or absence of catalysts, the purity of reactants and many times stirring/mixing also are factors.Size of a particles.Surface area.Temperature.Size of a substances.Whether a catalyst is present or not etc.
What affects the rate of diffusions?
Temperature, Concentration and size of molecules :)
What affects the rate of a reaction?
The rate of a reaction increases if: · The temperature is increased · The concentration of a dissolved reactant is increased · The pressure of a reacting gas is increased · Solid reactants are broken into smaller pieces · A catalyst is used
What physical factors control the rate of chemical reactions?
Physical factors that control the rate of chemical reactions include temperature, pressure, concentration of reactants, and surface area of the reactants. Temperature influences the kinetic energy of particles, pressure affects the collision frequency of molecules, concentration determines the number of reactive collisions, and surface area determines the contact area between reactants.
A factor that affects the rate of reaction?
There are several factors that affect the rate of reaction: -The surface area available. -Temperature -Availability of catalyst. -Concentration, if a/the reactant(s) is/are solutions. -Pressure, if a/the reactants(s) is/are gases. -Reactivity of reactants. -Activation energy of the reaction.
