What is the mechanism for the reaction between bromine and cyclohexane and state the conditions favor the reaction?
electrophilic substitution. and UV light or heat is required to all the reaction to proceed
What was the purpose of the sodium hydroxide in this schotten-baumann?
Addition of a base is required to absorb acidic proton (chloride acid) that formed from alcohol and tosylate, or the reaction will not proceed
Are substrate and catalyse the same thing?
No! A substrate is a reagent in a chemical reaction. Catalyse is the verb form of catalyst; a catalyst is a chemical species that participates in lowering the energy barrier of a chemical reaction and allow a reaction to occur more rapidly. A catalyst is not consumed in a reaction and therefore only a small amount of catalyst is required in any reaction (if required at all), whereas a substrate must be present in the proper stoichiometric amount to allow a reaction to proceed as it is consumed.
What governs the rate of chemical reactions?
Generally, the energy required to initiate the reaction. Reactions that release energy (exothermic) can proceed faster than those that require energy to be added (usually in the form of heat energy).
How is a catalyst different from the reactants and products of a chemical reaction?
Unlike reactants, catalysts are not used up during a reaction. They merely speed up the reaction (or allow it to proceed).

How do an enzymes speed up chemical reactions in cells?
They lower the activation energy required for the reaction to proceed.
How does an enzyme speed up its reaction?
Enzymes speed up a reaction by lowering the activation energy. This is the amount of energy required to start the reaction. By lowering the activation energy, the reaction can proceed much more quickly.
What is a substance that enables a chemical reaction to proceed under different conditions?
A catalyst is a substance that enables a chemical reaction to proceed under different conditions. It lowers the activation energy required for the reaction to occur, allowing it to happen more quickly or at a lower temperature or pressure. The catalyst itself remains unchanged in the reaction and can be reused multiple times.
Which reaction cannot proceed without an activation energy?
An exergonic reaction
What was the purpose of the sodium hydroxide in this schotten-baumann?
Addition of a base is required to absorb acidic proton (chloride acid) that formed from alcohol and tosylate, or the reaction will not proceed
What can proceed in the opposite direction?
Reversible reaction
What do mean by extent of reaction?
Extent of the reaction measures how far a reaction will proceed before establishing equilibrium state .
Why is light reaction of photosynthesis essential for the dark reaction to proceed?
why light reaction of photosynthesis is essential before the dark reaction can procced?
Is heating a flask on a hot plate an example of activation energy beginning to react?
No, heating a flask on a hot plate is not an example of activation energy beginning to react. Activation energy refers to the minimum amount of energy required for a chemical reaction to occur, and it is not related to heating a flask. Heating a flask on a hot plate simply refers to the process of applying heat to the flask, which can facilitate a reaction by increasing the temperature and providing the necessary energy for the reaction to proceed.
Are substrate and catalyse the same thing?
No! A substrate is a reagent in a chemical reaction. Catalyse is the verb form of catalyst; a catalyst is a chemical species that participates in lowering the energy barrier of a chemical reaction and allow a reaction to occur more rapidly. A catalyst is not consumed in a reaction and therefore only a small amount of catalyst is required in any reaction (if required at all), whereas a substrate must be present in the proper stoichiometric amount to allow a reaction to proceed as it is consumed.
What chemical reaction that can proceed forward or backward is a?
You think probable to a reversible reaction.
