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."

How will the temperature affect the spontaneity of a reaction with positive h and s?
A high temperature will make it spontaneous.
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 would increasing the temperature affect the rate of a reaction?
Doubles it
How does changing the temperature of solutions affect the rate of reactions?
In most cases, increasing the temperature increases the rate of the reaction.
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 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 is temperature affect the spontaneity of a reaction with positive H and S?
An increase in temperature generally makes reactions with positive enthalpy (ΔH) and positive entropy (ΔS) values more spontaneous. This is because at higher temperatures, the increase in the TΔS term can outweigh the positive ΔH term in the Gibbs free energy equation (ΔG = ΔH - TΔS), resulting in a more negative ΔG and thus a more spontaneous reaction.
How does temperature affect spontaneity?
If H and S have the same sign, the temperature will determine spontaneity.
Predict whether the changes in enthalpy entropy and free energy will be positive or negative for the freezing of water and explain your predictions How does temperature affect the spontaneity?
The changes in enthalpy, entropy, and free energy are negative for the freezing of water since energy is released as heat during the process. At lower temperatures, the freezing of water is more spontaneous as the negative change in enthalpy dominates over the positive change in entropy, making the overall change in free energy negative and leading to a spontaneous process.
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.
Blobs in the bottle affect the water temperature the reaction?
Blobs in the bottle could potentially hinder the transfer of heat in the reaction, affecting the water temperature by either trapping or releasing heat. This could lead to an inaccurate measurement of the reaction's temperature or alter the rate of the reaction. It's important to ensure the bottle is free of any obstructions to obtain reliable results.
How does temperature concentration and acidity affect reaction rate?
Generally increasing the temperature and concentration the reaction rate is higher.
How does heat affect the rate of the reaction?
Increasing the temperature the reaction rate increase.
How does the amount of copper chloride affect the temperature of the reaction?
The amount of copper chloride in a reaction can affect the temperature by influencing the rate of the reaction. Adding more copper chloride can increase the rate of reaction, leading to a faster rise in temperature. Conversely, reducing the amount of copper chloride can slow down the reaction and result in a lower temperature change.
