An increase in room temperature would not necessarily increase the rate of reaction. While it can often increase reaction rates due to the increased kinetic energy of molecules, there are instances where the reaction might not be temperature-sensitive. The other factors listed—reactants being more concentrated, presence of a catalyst, and presence of an enzyme—will typically increase the rate of a reaction.

What are different factors that affect the rates of chemical reactions?
Some different factors that affect the rates of chemical reactions include whether or not a catalyst is present, the concentration of the reactants, temperature of the reactants, & pressure in the case of gas phase reactions.
What are 4 things that affect the rate of a reaction?
1. The concentration of the substances. 2. The temperature. 3. The surface area of the particles. 4.The presence of a catalyst.
How are rates of reaction determine?
Rates of reaction are determined by factors such as concentration of reactants, temperature, presence of a catalyst, and surface area. Increasing the concentration of reactants and temperature generally increases reaction rates, while adding a catalyst can speed up the reaction by providing an alternative pathway with lower activation energy. Additionally, increasing the surface area of the reactants can enhance reaction rates by increasing the number of collisions between particles.
Is a substance that increases the rate of a chemical reaction.?
Factors affecting the reaction rate: - Concentrations of the reactants- Temperature- Pressure- Stirring- Catalysts- Granulometry (and the surface area) of the reactants- Reaction order- Type of the reaction- The solvent used- External factors as irradiationetc.
What affects how fast a chemical reaction takes place?
The nature of the reactants, the temperature (and pressure if gases are involved), and the presence of a catalyst.
What are the 5 important factors that influence the rate of a chemical reaction?
The key factors that influence the rate of a chemical reaction are concentration of reactants, temperature, presence of a catalyst, surface area of reactants, and the nature of the reactants and products.
What are different factors that affect the rates of chemical reactions?
Some different factors that affect the rates of chemical reactions include whether or not a catalyst is present, the concentration of the reactants, temperature of the reactants, & pressure in the case of gas phase reactions.
Which methods will usually cause a reaction to speed up?
Combining the reactants at a lower temperature. Reducing the concentration of reactants. Grinding one of the reactants into a powder. Removing the catalyst.
What are 4 things that affect the rate of a reaction?
1. The concentration of the substances. 2. The temperature. 3. The surface area of the particles. 4.The presence of a catalyst.
What factors can influence the rate of reaction?
Concentration of reactants and time; also: temperature, pressure, stirring, added catalyst, the type of solvent, surface area of reactants, effect of other physical factors as irradiation, etc.
Which of these is not a factor influencing the rate of a chemical reaction?
The color of the reactants is not a factor influencing the rate of a chemical reaction. Factors that do influence reaction rate include temperature, concentration of reactants, presence of a catalyst, and surface area of reactants.
What effects the rate of reaction?
1.concentration of reactants 2.temperature 3.nature of reactants 4.presence of catalyst 5.surface area of reactants 6.radiation
What are three factors of the speed at which a chemical reaction happens?
temperature presence or absence of a catalyst concentration of reactants
On what does the rate constant depend?
The rate constant depends on factors such as temperature, concentration of reactants, and presence of a catalyst.
How can one increase the rate of reaction?
One can increase the rate of a chemical reaction by increasing the temperature, concentration of reactants, surface area of reactants, or using a catalyst.
What is the difference between a homogeneous catalyst and a heterogeneous catalyst?
The difference between a homogeneous and a heterogeneous catalyst is that in a heterogeneous catalyst, it is in a different phase from the reactants. However, in a homogeneous catalyst, it is in the same phase as the reactants.
How are rates of reaction determine?
Rates of reaction are determined by factors such as concentration of reactants, temperature, presence of a catalyst, and surface area. Increasing the concentration of reactants and temperature generally increases reaction rates, while adding a catalyst can speed up the reaction by providing an alternative pathway with lower activation energy. Additionally, increasing the surface area of the reactants can enhance reaction rates by increasing the number of collisions between particles.
