What is the difference between a thermodynamically favorable and a thermodynamically unfavorable reaction?

Enthalpy change is not the only consideration for whether a reaction is favorable. However, if the enthalpy change is large, it is usually the dominant factor in determining favorability. Therefore, reactions that have a large, negative tend to be favorable, because the reaction usually releases energy when it occurs. Reactions that have a large, positive tend to be unfavorable as written, because the reaction usually requires energy to occur.

How does the presence of enzymes affect the equilibrium position of the breakdown of carbohydrate into glucose?
Enzymes cannot affect the equilibrium of a reaction, nor can they cause a thermodynamically unfavorable reaction to proceed. They are catalysts and can only alter the activation energy and therefore the rate of the reaction.
What is the meaning of thermodynamically favored reactions?
When a chemical reaction is described as being "thermodynamically favored," it means that it requires a great deal of activation energy for it to occur.
If an enzyme is exposed to an unfavorable pH?
Enzymes shows different enzyme activity in different pH value.If the pH is high or low than the optimum pH there is a decrease in the activity of the enzyme.But if the pH is very high or very low it may lead to the deactivation of the enzyme.
Does the temperature of the water affect the reaction?
There are many reactions in which we have to closely monitor the temperature of the water. If we want to form a thermodynamically stable product, when we have certain reactants as a starting material, it is advisable to increase the temperature of the water. Concentration, particle size, catalyst are some factors that can affect the rate of reaction.
What is the difference between normal reaction and abnormal reaction?
Normal reaction happens when the reaction is normal. Abnormal reaction happens when the reaction is abnormal.
When can you determine a chemical reaction will occur?
Thermodynamically favorable reaction will occur. Also, if the neutral element is higher in the activity series than the charged element, then the reaction will occur.

In a enzyme reaction is exposed to an unfavorable pH what happens to the speed of the reaction?
catalyzed reaction
If an enzyme reaction is exposed to an unfavorable pH what happens to the speed of the reaction?
It is reduced
When the actual free energy change of a reaction change in G has a numerical value of less than zero negative number what will happen?
When the delta G is negative the reaction is said to be spontaneous or in other words favorable. It also means the reaction is irreversible once full product concentration is reached. If delta G is positive, the reaction is unfavorable thus can easily be reversed. If it is zero it is at equilibrium.
Does completeness of a reaction imply that the reaction cannot be reversed?
This is not entirely true.It depends upon the reaction.Some reaction which are reversible can be reversed when suitable force is applied in the opposite direction.Here the force implies Pressure and heat.
Why are the elements of the 18th group of the periodic table so unreactive?
Group 18 (noble gases) of the periodic tabledoes not react with other elements because they have a complete outermost shell and they are stable as well. However,Xenon reacts with some elements.
What is the difference between hydroxylation and oxidation reaction?
There is no difference, these are 2 names for an identical reaction.
Is there a time difference between action and reaction forces?
No there is no difference between action and reaction forces!
