What does the term spontaneous mean in a chemical reaction?
Spontaneous in a chemical reaction means that the reaction occurs naturally without any external influence once started. It is driven by the inherent properties of the reactants and products, leading to a decrease in free energy and an increase in entropy.
A chemical reaction has a positive ΔH value and a positive ΔS value Under what conditions is the reaction spontaneous?
The reaction will be spontaneous at high temperatures (T) where TΔS > ΔH, according to Gibbs free energy equation, ΔG = ΔH - TΔS. At high enough temperatures, the TΔS term can outweigh the positive ΔH term, leading to a negative ΔG value and a spontaneous reaction.
What is the term used to describe all the life sustaining chemical reactions within the body?
The term you are looking for is metabolism. Metabolism includes all the chemical reactions that occur in the body to maintain life, such as converting food into energy, building and repairing tissues, and removing waste products.
Which term describes energy that is required to get chemical reactions started?
Activation energy is the term used to describe the energy required to start a chemical reaction by breaking the initial bonds between atoms or molecules. This energy barrier must be overcome in order for the reaction to proceed.
How is the term catalyst related to the term enzymes?
Enzymes are biological catalysts that speed up chemical reactions in living organisms. Catalysts, in general, are substances that increase the rate of a chemical reaction without being consumed in the process. Enzymes are a specific type of catalysts that are essential for various biological processes.
A chemical reaction has a positive H value and a positive S value Under what conditions is the reaction spontaneous?
The spontaneity of a reaction is determined by the sign of the Gibbs free energy (ΔG). If both enthalpy (H) and entropy (S) are positive, the reaction can be spontaneous at high temperatures where the TΔS term outweighs the positive ΔH term, resulting in a negative ΔG. This means the reaction will be spontaneous at elevated temperatures.
What does the term spontaneous mean in a chemical reaction?
Spontaneous in a chemical reaction means that the reaction occurs naturally without any external influence once started. It is driven by the inherent properties of the reactants and products, leading to a decrease in free energy and an increase in entropy.
WHAT TERM DESCRIBES ENERGY THAT REQUIRES TO GET CHEMICAL REACTIONS STARTED?
Activation energy describes the energy that is required to get chemical reactions started.
What term refers to protenis that speed up chemical reactions in living things?
Enzymes are proteins that speed up chemical reactions in the body.
What term is used in to define substances that participate in chemical reactions?
reactants
What term is used to define substances that a participate in chemical reactions?
reactants
What are anabolic reactions, and what is another term used to describe them?
Anabolic reactions are chemical processes in the body that build molecules and require energy. Another term used to describe them is biosynthetic reactions.
What does the term sugarless or sugar free mean?
It means the natural sugars have been replaced with chemical sweeteners. These can cause allergic reactions and other problems.
What is term define as new substances formed from chemical reactions?
The term used to describe a new substance formed from a chemical reaction would be "product."
What is the term to define all the chemical reactions required to sustain life?
metabolism
What is the term used to describe the sum of all chemical reactions in an organism?
metabolism
What term describes energy that is required to get chemical reactions started?
Activation energy describes the energy that is required to get chemical reactions started.
