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.
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).
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.
Substance that increases rate of chemical reactions?
catalyst
What is the substance that changes the rate of chemical reactions without being changed called?
In biological systems an enzyme speeds up the reaction without changing it. In other chemical reactions this function is achieved by a catalyst.
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 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.
This is the rate at which a substance undergoes a chemical change?
This is called reaction rate.
Do enzymes decrease the rate of chemical reactions?
No, they Increase the speed of chemical reactions
What is the rate of chemical reaction is?
The rate of chemical reactions is how long a chemical reaction takes to finish.
What type of protein regulates nearly all chemical reaction in a cell?
An enzyme is a protein that speeds up the rate of chemical reactions.
How particle collisions that affect the rate of chemical reactions?
When the number of particle collisions increase the rate of chemical reactions also increase.
What 4 things can increase the rate of a chemical reaction?
Concentrations of reactants; concentrations of products; changes in temperature (usually higher temperatures favor faster reactions); catalyst; for some reactions, incident light; and, for reactions with a volume change, changes in pressure.
The process that changes rock into one or more new compounds is called?
when rocks undergo chemical changes as a result those reactions are called chemical weather.please rate and subscribe this answer
