Synthesis reactions such as dehydration synthesis.
For a reaction to proceed the there must be a net decrease in the Gibbs Free Energy of the system.
The Gibbs Free Energy is made up of two terms:
Enthalpy or Heat Content H
Entropy S
For a reaction in which the entropy is increasing to proceed there would have to be a sufficient release of heat content (enthalpy) such that
Change in Free Energy G would be negative, ie decrease...

What two types of reactions occur during photosynthesis?
The two reactions which occur during photosynthesis are light reaction and dark reaction. Light reaction takes place only in the presence of light. Dark reaction can occur with or without light.
How does the phenomenon of glowing grass occur in nature?
The phenomenon of glowing grass occurs in nature due to bioluminescent organisms, such as certain types of fungi or bacteria, that emit light as a result of a chemical reaction within their cells. This light emission is often seen in dark or low-light environments and can create a visually striking effect.
What are the two types of metabolism in the human body?
Exergonic reaction: This type of reaction releases more energy than puts in, and it occurs spontaneously.Endergoic reaction: Absorbs free energy from the surroundings. This type of reaction stores free energy in the bonds of molecules.
When does a chemical reaction reaches equilibrium?
equilibrium means the rate of forward reaction = rate of backward reaction... there are three types of equilibrium 1. amount of products > amount of reactants 2. amount of products = amount of reactants 3. amount of products < amount of reactants
Are neurotransmitters always stimulatory?
No, neurotransmitters can be either stimulatory or inhibitory. Stimulatory neurotransmitters excite the receiving neuron and increase the likelihood of an action potential, while inhibitory neurotransmitters decrease the likelihood of an action potential. Both types are essential for maintaining a balance in neural signaling within the brain and nervous system.
What types of reactions would decrease the entrophy within a cell?
CO(g)+3H2(g)->CH4(g)+H2O(g)
Which accounts for the increase in the rate of reaction when a catalyst is added to a reaction system. Does the entropy of the reaction increase?
When two molecules react with each other they must form a transition state. The higher the energy of the transition state the less likely it is for the two molecules to react with each other. Catalysts lower the energy of the transition state. This makes it more likely for molecules to react with one another, which speeds up the overall reaction. Entropy is unrelated. Reactions that break apart molecules increase entropy. Reactions that combine molecules together diminish entropy. Both types of reactions can be sped up by catalysts.
What two types of energy change can occur in a chemical reation?
Two types of energy change that can occur in a chemical reaction are endothermic or exothermic. An exothermic reaction causes an increase in temperature and an endothermic reaction causes a decrease in temperature.
How does change in phase affect entropy changes in a reaction?
A change in phase (e.g. solid to liquid) typically involves an increase in entropy due to an increase in molecular disorder and freedom of movement. However, entropy changes can vary depending on the specific conditions of the reaction.
How does a change in phase affect entropy changes in a reaction?
It happens because, even in the same compound, atoms/molecules in different phases have different types of behaviour. For example, unlike solids, liquid and gas molecules can 'flow' around.
What are types of isolation?
Answer a.speed of the reaction. b.products of the reaction. c.pH of the reaction. d.temperature of the reaction
Why would you administer one injection type or the other on a cow?
If by injection types you are referring to IM, SQ, IV etc. the reason can be to prolong the action of the drug, decrease the possibility of an injection site reaction, or in some instances a systemic reaction or even anaphylactic shock.
What types of reactions is photosynthesis?
endergonic reaction
How do stimulants and depressants affect reaction times?
Stimulants (such as caffeine) can decrease reaction times by increasing alertness and speeding up cognitive processes. Depressants (such as alcohol) can impair reaction times by slowing down the central nervous system and affecting coordination and decision-making abilities. Both types of substances can have a significant impact on reaction times depending on the dose and individual tolerance.
What Two types of this are boiling and evaporation?
decrease and increase
What are types of chemical reaction?
1 combination reaction. 2. displacement reaction. 3.decomposition reaction. 4.displacement reaction.
