How will the temperature affect the spontaneity of a reaction with positive h and s?
A high temperature will make it spontaneous.
How will temperature affect the spontaneity of a reaction positive delta h and delta s?
∆G = ∆H - T∆S and for it to be spontaneous, ∆G should be negative. If both ∆H and ∆S are positive, in order to get a negative ∆H, the temperature needs to be elevated in order to make the ∆S term greater than the ∆H term. So, I guess the answer would be "the higher the temperature, the more likely will be the spontaneity of the reaction."
Do catalysts affect temperature?
A catalyst affects the speed of a chemical reaction. If the chemical reaction gives off heat, the reaction may affect the temperature, but the catalyst by itself doesn't affect the temperature.
How does temperature affect reaction rate hot?
The Hotter the temperature, the faster the particle moves. During the reaction, atoms transfer in different molecules (or compounds), therefore the temperature does affect the speed of the reaction.
How is enthalpy related to the spontaneously of a reaction?
H < 0 contributes to spontaneity.
How will the temperature affect the spontaneity of a reaction with positive h and s?
A high temperature will make it spontaneous.
How can the spontaneity of a reaction be reversed?
The spontaneity of a reaction can be reversed by changing the conditions such as temperature, pressure, or concentration of reactants, or by adding a catalyst.
How does temperature affect spontaneity?
If H and S have the same sign, the temperature will determine spontaneity.
How will temperature affect the spontaneity of reaction with positive H and S?
A high temperature will make it spontaneous.
How does temperature affect the spontaneity of a reaction?
Increasing the temperature makes a reaction spontaneous in some situations.
How will temperature affect the spontaneity of a reaction with positive triangle H and triangle S?
For a reaction with a positive enthalpy change (ΔH > 0) and a positive entropy change (ΔS > 0), the spontaneity is influenced by temperature through the Gibbs free energy equation: ΔG = ΔH - TΔS. As temperature increases, the TΔS term becomes larger, which can make ΔG more negative, thereby favoring spontaneity. Therefore, at higher temperatures, the reaction is more likely to be spontaneous, while at lower temperatures, it may not be spontaneous.
How will temperature affect the spontaneity of a reaction positive delta h and delta s?
∆G = ∆H - T∆S and for it to be spontaneous, ∆G should be negative. If both ∆H and ∆S are positive, in order to get a negative ∆H, the temperature needs to be elevated in order to make the ∆S term greater than the ∆H term. So, I guess the answer would be "the higher the temperature, the more likely will be the spontaneity of the reaction."
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.
How is enthalpy related to spontaneity of a reaction?
S > 0 contributes to spontaneity.
Do catalysts affect temperature?
A catalyst affects the speed of a chemical reaction. If the chemical reaction gives off heat, the reaction may affect the temperature, but the catalyst by itself doesn't affect the temperature.
How is the speed of chemical reaction related to the spontaneity of the reaction?
The speed of a given chemical reaction is directly responsible for spontaneity of the reaction. The reaction force and effect is contingent upon the speed of the reaction. The faster the reaction, the more force will be produced.
How is temperature affect the spontaneity of a reaction with positive H and S?
∆G = ∆H - T∆S and ∆G has to be negative for the reaction to be spontaneous. So, ultimately the effect of temperature will depend on the value of ∆H. If ∆H is negative, and ∆S is positive, then temperature won't matter, and reaction will be spontaneous. If ∆H is positive, and ∆S is positive, then a high temperature will favor spontaneity. If ∆H is negative and ∆S is negative, then a low temperature will favor spontaneity. So, the answer to your question is the higher the temperature the more likely the reaction will occur spontaneously.
