Will an increased temp and an increased concentration speed up a chemical reaction?
Generally, yes. Unless the product of the reaction should be ammonia for example, where a decreased temperature is needed. A catalyst from the transition metals will speed up a reaction too, for example a nickel catalyst in the process of the hydrogenation of margerine as it lowers the activation energy needed for the reaction to start. Increased pressure will also speed up the reaction, no matter what reaction is occurring.

What two factors speed up rates of chemical reaction and weathering?
Two factors that can speed up rates of chemical reaction and weathering are increased temperature and higher concentration of reactants or weathering agents. Higher temperature provides more energy for molecules to react, while increased concentration provides more opportunities for collisions between reactant molecules.
What speeds up rates of chemical reaction and weathering in rocks and soils?
Factors such as increased temperature, higher concentration of reactants, and the presence of catalysts can speed up chemical reactions in rocks and soils. Additionally, physical processes like abrasion, erosion, and the expansion and contraction of rocks due to freezing and thawing can accelerate weathering.
What effects the rate constant of a reaction?
The temperature of the system
A chemical reaction occurs between sodium hydroxide and hydrogen chloride Adding more sodium hydroxide to the reaction causes it to speed up If you add more of a reactant such as sodium hydroxide?
A chemical reaction occurs between sodium hydroxide and hydrogen chloride. Adding more sodium hydroxide to the reaction causes it to speed up. If you add more of a reactant, such as sodium hydroxide, can it be considered a catalyst? Why or why not?
What two factors speed up rates of chemical reaction and weathering in rocks and soils?
Two factors that can speed up rates of chemical reactions and weathering in rocks and soils are increased temperature and presence of water. Higher temperatures typically increase the kinetic energy of molecules, leading to more frequent collisions and faster reaction rates. Water can act as a solvent, facilitating chemical reactions, and also participate in processes like hydrolysis and hydration, accelerating weathering.
What are two ways the speed of a chemical reaction can be increased if both of the reactants are aqueous solutions?
The speed of a chemical reaction can be increased by increasing the temperature, as higher temperatures provide more kinetic energy to the reactant molecules, leading to more frequent and energetic collisions. Another way is to increase the concentration of the reactants, as a higher concentration provides more reactant particles in a given volume, increasing the likelihood of collisions and reactions.
What is the speed of a chemical reaction is increased by?
Most effectively increased speed by temperature increase and adding a catalyst ( = enzymes in biological reactions. Further measures: raising concentration of reactants, grinding solids, mixing, for some reactions: put in light scource
What two factors speed up rates of chemical reaction and weathering?
Two factors that can speed up rates of chemical reaction and weathering are increased temperature and higher concentration of reactants or weathering agents. Higher temperature provides more energy for molecules to react, while increased concentration provides more opportunities for collisions between reactant molecules.
How does a enzyme increase the speed of a reaction?
The enzyme reduces the activation energy of the reaction, therefore chemical reaction speeds are increased.
What effects does temperature have on chemical changes?
Generally the speed of reaction increase when the temperature is increased.
Does glucose increases the speed of chemical reaction?
Glucose can act as a substrate for biological reactions, but it does not inherently increase the speed of chemical reactions. The rate of a chemical reaction is determined by factors such as temperature, concentration of reactants, and presence of catalysts.
What are three factors of the speed at which a chemical reaction happens?
temperature presence or absence of a catalyst concentration of reactants
What identification it refers to the speed of a chemical process?
The identification of the speed of a chemical process is referred to as the reaction rate. It represents how quickly reactants are consumed or products are formed during a chemical reaction. The reaction rate is typically quantified as the change in concentration of a reactant or product per unit time.
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.
What can speed up a chemical reaction by decreasing?
chemical reaction
What is chemical reaction in an enzyme?
to speed up a chemical reaction
Why does increased temperature speed up a reaction?
The motion of chemical entities increase with the temperature and the probability of collisions also increase.
