What is the substance of a chemical reaction that accelerates?
A substance that accelerates a chemical reaction is called a catalyst. Catalysts work by lowering the activation energy needed for a reaction to occur, which speeds up the reaction without being consumed in the process.
Definition energy needed for a chemical reaction is decreased by what?
The energy needed for a chemical reaction, known as activation energy, can be decreased by the presence of a catalyst. Catalysts work by providing an alternative reaction pathway with a lower activation energy, thereby increasing the reaction rate without being consumed in the process. Additionally, factors such as increasing temperature or concentration can also decrease the effective activation energy needed for a reaction to occur.
What is an example of chemical cellular work?
An example of chemical cellular work is the synthesis of proteins. This process involves combining amino acids to form complex protein structures within the cell. Energy is required for this chemical reaction to occur, which is provided by cellular processes like ATP hydrolysis.
What is any molecule that speeds up a chemical reaction?
A molecule that speeds up a chemical reaction is called a catalyst. Catalysts work by reducing the activation energy needed for a reaction to occur, which increases the rate of the reaction without being consumed in the process.
How taste buds work?
Chemical reaction
How does a fire extinguisher stop a combustion reaction?
A fire extinguisher stops a combustion reaction by removing one or more of the essential components of fire: heat, fuel, or oxygen. Different types of extinguishers work through various mechanisms; for example, water extinguishers cool the fire by absorbing heat, while foam extinguishers smother the flames, cutting off the oxygen supply. Dry chemical extinguishers interrupt the chemical reaction itself, effectively disrupting the combustion process. By targeting these elements, fire extinguishers effectively halt the fire's ability to sustain itself.
Enzymes work by lowering the what?
Also known as activation energy. threshold energy or you can also say enzymes lower the energy barrier
Substances that hasten chemical reaction time without themselves undergoing changes are called?
catalysts. These substances work by providing an alternative pathway for the reaction to occur more rapidly, lowering the activation energy needed for the reaction to proceed. Catalysts do not undergo permanent changes in their chemical composition during the reaction.
Is burning a fire work a physical or chemical change?
chemical
Why is energy needed in a reaction?
Energy is needed in a reaction to break existing chemical bonds in the reactants and form new bonds to create products. This process requires activation energy to overcome the barriers between reactants and products. Additionally, energy is needed to drive the reaction towards completion and ensure that the reaction proceeds in the desired direction.
What does chemical work mean?
Chemical work refers to the energy associated with a chemical reaction or transformation. It involves the breaking and forming of chemical bonds, and is often measured in terms of the change in the internal energy of a system during a reaction. This energy can be used to do work or drive other processes.
What energy is used for a fire to work?
Chemical energy!
