What else can I help you with?
What speeds up reactions?
A catalyst. It does do by decreasing the energy required for the reaction to take place (activation energy).
What are biochemical reactions?
Biochemistry is the study of a chemical process in living things. Biochemists study microorganisms like proteins and carbohydrates. The process is how they do it, by aid of microscopes, hypothesis and experimentation.
What is the effect of temperature on rates of reactions?
Typically heat will speed up a chemical reaction because it causes the actual atoms to move quicker and collide with each other causing a chemical reaction. For example a redox reaction where a electron is passed between atoms.
What are the two attributes of a catalyst?
A catalyst must change the rate of a chemical reaction. It must be unchanged at the end of the reaction.
How does heat affect light sticks?
Generally speaking, heat increases the rate of chemical reactions; in the specific case of light sticks, it means they glow more brightly (and don't last as long).
Substance that increases rate of chemical reactions?
catalyst
Is decay rate a chemical or physical property?
Decay rate is a chemical property, as it relates to the rate at which a substance undergoes chemical reactions or transformations over time.
What is the substance that changes the rate of chemical reactions without being changed called?
A substance that changes the rate of a chemical reaction without being consumed is called a catalyst. Catalysts work by lowering the activation energy required for the reaction to occur, thereby speeding up the reaction process.
What is a protein that changes the rate of chemical reactions?
its called an enzyme
How does temperature aff ect the rate of chemical changes?
An increase in temperature increases the rate of most, but not all, chemical reactions.
What changes when the amount of a substance changes?
When the amount of a substance changes, it can affect the concentration, density, and reactivity of the substance. In chemical reactions, changing the amount of a substance can also impact the equilibrium position and the rate of reaction. Additionally, changing the amount of a substance can influence its physical properties, such as melting point, boiling point, and solubility.
What is the significance of a substance with a pH of 3 in chemical reactions?
A substance with a pH of 3 is considered acidic. This acidity can affect chemical reactions by influencing the rate and outcome of reactions. Acids can donate protons, which can react with other substances to form new compounds or change the properties of existing compounds. The pH level of a substance can therefore play a crucial role in determining how it interacts with other substances in chemical reactions.
This is the rate at which a substance undergoes a chemical change?
This is called reaction rate.
What is a substance that helps chemical reactions?
A substance that helps chemical reactions is called a catalyst. It speeds up the rate of a reaction by providing an alternative pathway with lower activation energy. Catalysts are not consumed in the reaction and can be used repeatedly.
How does dissolvation affect the rate of chemical reactions in aqueous solutions?
Dissolvation can increase the rate of chemical reactions in aqueous solutions by allowing reactant molecules to come into closer contact and interact more easily. This is because dissolving a substance in water breaks it down into smaller particles, increasing the surface area available for reactions to occur. As a result, dissolvation can speed up the rate of chemical reactions in aqueous solutions.
What is the substance called that helps chemical reactions happen in the body?
Enzymes are the substances that help chemical reactions occur in the body. These protein molecules act as catalysts, speeding up the rate of biological reactions without being consumed in the process.
What is the rate of chemical reaction is?
The rate of chemical reactions is how long a chemical reaction takes to finish.
