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.
According to gibb's free energy equation GH-TS When is a reaction always spontaneous?
A reaction is always spontaneous when the change in Gibbs free energy (ΔG) is negative. This occurs when the enthalpy change (ΔH) is negative (exothermic reaction) and the entropy change (ΔS) is positive, particularly at all temperatures. Even if ΔH is positive, if ΔS is sufficiently large and positive, the reaction can still be spontaneous at high temperatures, as the term TΔS will outweigh ΔH.
Is candle burning a spontaneous or non spontaneous reaction?
Candle burning is a spontaneous reaction. It is an exothermic reaction that occurs naturally and releases heat and light energy as the wax is being oxidized in the presence of oxygen from the air.
How does Gibbs free energy predict spontaneous?
If G < 0, the reaction is spontaneous.
Ask us anythingWhich of the following describes a nonspontaneous reaction?
a non spontaneous reaction is a reaction that doesnt occur naturally and it normally tends to favor the reactants of a chemical reaction. Another thing is that it doesnt really produce free energy
Is an exothermic reaction always spontaneous?
No, an exothermic reaction is not always spontaneous. The spontaneity of a reaction depends on factors such as temperature, pressure, and the entropy change of the system.
A chemical reaction has a positive H value and a positive S value Under what conditions is the reaction spontaneous?
The spontaneity of a reaction is determined by the sign of the Gibbs free energy (ΔG). If both enthalpy (H) and entropy (S) are positive, the reaction can be spontaneous at high temperatures where the TΔS term outweighs the positive ΔH term, resulting in a negative ΔG. This means the reaction will be spontaneous at elevated temperatures.
Is the reaction exergonic and spontaneous or not?
Yes, the reaction is exergonic and spontaneous.
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.
A reaction that occurs without provocation from an outside system is?
A spontaneous reaction.
Is the reaction spontaneous or non-spontaneous when considering the keyword "spontaneous vs non-spontaneous"?
In the context of "spontaneous vs non-spontaneous," a reaction is considered spontaneous if it occurs on its own without needing external influence. On the other hand, a non-spontaneous reaction requires external energy input to occur.
Are chemical reactions always spontaneous when H is negative and S is negative?
No, when H and S are both negative, the reaction will only be spontaneous below a certain temperature
What is the reverse of a spontaneous reaction, and how does it differ from a nonspontaneous reaction?
The reverse of a spontaneous reaction is a nonspontaneous reaction. In a spontaneous reaction, the reaction occurs naturally without any external influence, while in a nonspontaneous reaction, external energy input is required for the reaction to occur.
According to the Gibbs free energy equation G H - TS when is a reaction always spontaneous?
when H is negative and S is positive
Is candle burning a spontaneous or non spontaneous reaction?
Candle burning is a spontaneous reaction. It is an exothermic reaction that occurs naturally and releases heat and light energy as the wax is being oxidized in the presence of oxygen from the air.
Is a reaction with an equilibrium constant greater than 1 considered to be a spontaneous reaction?
A reaction with an equilibrium constant greater than 1 is considered to be a spontaneous reaction.
Which best describes a galvanic cell a battery containing a non spontaneous reaction a battery containing an acid and a base a battery containing a spontaneous redox reaction a battery that requires?
spontaneous redox reaction
