How do you determine whether a reaction is spontaneous or non spontaneous?
The first of two factors that determine whether a reaction is spontaneous or non-spontaneous is entropy. The second is energy. For a reaction to be spontaneous, it must have both of these factors.
What factors generally determine whether a reaction happens or not?
Enthalpy and entropy.
Two factors that determine fate of a chemical reaction in a living cell?
Direction and Rate
Will exothermic energy-releasing chemical reactions not occur?
Whether or not a reaction occurs is governed by its Gibbs free energy, or spontaneity. We will refer to this as ∆G. When ∆G is less than 0, the reaction is spontaneous and hence it will occur. On the other hand, when ∆G is more than 0, the reaction is not spontaneous and will not take place. ∆G is governed by several factors: 1) ∆H - the enthalpy of the reaction. This is what you mean by reactions that release energy. These energy-releasing reactions are termed as "exothermic reactions". 2) ∆S - the entropy of the reaction. 3) T - the temperature. They are inter-related with the formula: ∆G = ∆H - T*∆S Therefore, the enthalpy of a reaction cannot determine its spontaneity as there are other factors (∆S and T) to consider as well. You also have to take note of activation energy barriers that have to be overcome before a reaction can take place! I hope this was helpful! :)
What factors determine the stopping distance?
Speed, reaction time, car's mass, tires, mechanical condition & type of brakes.
What are the factors that determine the length of an engagement?
What are the factors that determine the length of an engagement?
What has the author Oswald H Boltz written?
Oswald H. Boltz has written: 'Some factors which determine a schizophrenic (Dementia praecox) reaction in males'
Are chemical factors that determine traits?
The chemical factors that determine traits are genes.
What factors determine a biome?
Two factors that determine a biome are precipitation and temperature.
How can you predict which element are stable under natural condition and which element tend to under go chemical reaction?
There are two levels of chemical stability, one is whether the reaction in question releases energy in the form of heat or whether it creates more disorder. These two principal factors drive every chemical reaction that one will encounter from cradle to grave (baring any work involving nuclear reactors). They are formally known as entropy (change in disorder) and enthalpy (change in heat). These two factors taken together tell whether a reaction will happen or not (whether it is spontaneous or not). The easy way to find whether the reaction is favorable (spontaneous) or not is to look up the Gibb's free energy (in a table) for the products and the reactants and then subtract the sum of the reactants from the sum of the products. If the number is negative, then the reaction is spontaneous at room temperature. This concept takes quite a bit of work to master and accounts for the bulk of any chemistry text book, so don't expect to learn the answer overnight.
