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?
Factors that affect the rates of chemical reactions include temperature, concentration of reactants, surface area of reactants, presence of a catalyst, and the nature of the reactants (such as their reactivity).
What are 4 things that affect the rate of a reaction?
Four things that affect the rate of a reaction are temperature, concentration of reactants, presence of a catalyst, and surface area of solid 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.
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.
Which methods will usually cause a reaction to speed up?
Increasing the temperature, increasing the concentration of reactants, using a catalyst, and increasing the surface area of reactants are methods that can usually cause a reaction to speed up.
What are 4 things that affect the rate of a reaction?
Four things that affect the rate of a reaction are temperature, concentration of reactants, presence of a catalyst, and surface area of solid reactants.
What factors can influence the rate of reaction?
Factors that can influence the rate of a chemical reaction include concentration of reactants, temperature, presence of a catalyst, surface area of solid reactants, and pressure (for gaseous reactants). These factors affect the frequency of collisions between particles and the energy of those collisions, ultimately impacting the rate at which the reaction occurs.
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
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.
