Is it true or false that all chemical reactions require an initial input of energy called catalysis?
False. Not all chemical reactions require catalysis. Some reactions occur spontaneously, while others may require an initial input of energy in the form of activation energy. Catalysis is a process that lowers the activation energy required for a reaction to occur, but it is not necessary for all reactions.
What is the role of energy in chemical reactions?
Energy is required to break chemical bonds in reactant molecules in order to initiate a chemical reaction. This initial input of energy is called activation energy. In addition, energy is released or absorbed during a chemical reaction, which can result in changes in temperature.
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.
Why is G zero for a phase change?
G is zero for a phase change because at equilibrium, the Gibbs free energy of the system remains constant, indicating a balance between the energy required to break intermolecular forces in the initial phase and the energy released when forming new intermolecular forces in the final phase.
Chemical reactions cannot be easily?
Chemical reactions cannot be easily reversed or undone due to the fact that energy is often required to break existing chemical bonds and form new ones. Additionally, the resulting products of a chemical reaction may be different from the initial reactants, making it challenging to revert back to the original substances.

The initial reactions in photosynthesis are know as the?
The initial reactions in photosynthesis are known as the light-dependent reactions. These reactions occur in the thylakoid membranes of the chloroplast and involve the absorption of light energy to drive the conversion of water into oxygen, ATP, and NADPH.

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.
Why initial reaction is required to minus from final reaction?
The initial reaction is required to be subtracted from the final reaction to get the net reaction.
How do enzymes affect reactions?
Enzymes speed up chemical reactions by lowering the activation energy required for the reaction to occur. They do this by binding to reactant molecules and bringing them together in the correct orientation to facilitate the reaction. Enzymes are specific to certain substrates, so they only catalyze specific reactions.
Why is G zero for a phase change?
G is zero for a phase change because at equilibrium, the Gibbs free energy of the system remains constant, indicating a balance between the energy required to break intermolecular forces in the initial phase and the energy released when forming new intermolecular forces in the final phase.
The initial activation energy for the process of photosynthesis is?
The initial activation energy for the process of photosynthesis is the energy required to initiate the conversion of light energy into chemical energy. This energy is used to break the bonds in the reactants and start the photosynthetic reactions.
What are the initial symptoms of subacute sclerosing panencephalitis?
Initial symptoms include a change in behavior, irritability, memory loss, and difficulty in forming thoughts and solving problems.
What substances during chemical reactions are involved?
The initial substances in a chemical reaction are called reactants.
Are the saturated products formed from the addition reactions of unsaturated hydrocarbons more stable or less stable than the initial reactants?
The saturated product formed from the addition reactions of unsaturated hydrocarbons are more stable than the initial reactants.In general any chemical reaction that does not involve the input of vast amounts of energy to achieve (eg the smelting of ores) will produce products that are more stable than the reactants.
Chemical reactions cannot be easily?
Chemical reactions cannot be easily reversed or undone due to the fact that energy is often required to break existing chemical bonds and form new ones. Additionally, the resulting products of a chemical reaction may be different from the initial reactants, making it challenging to revert back to the original substances.
