The favorability or spontaneity of a reaction increases when during the course of a reaction?
the energy content and entropy both decrease
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?
Enthalpy- positive Entropy- decreasing Free energy- negative
How will the temperature affect the spontaneity of a reaction with positive h and s?
A high temperature will make it spontaneous.
What happens to the entropy in the reaction?
Entropy increases. In a reaction comprised of sub-reactions, some sub-reactions may show a decrease in entropy but the entire reaction will show an increase of entropy. As an example, the formation of sugar molecules by living organisms is a process that shows decrease in entropy at the expense of the loss of entropy by the sun.
What reaction would have an increased entropy?
At high temperature the entropy increase.
The favorability or spontaneity of a reaction increases when during the course of a reaction?
the energy content and entropy both decrease
What kind of changes contribute to spontaneity?
An increase in entropy.
How is enthalpy related to spontaneity of a reaction?
S > 0 contributes to 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?
Enthalpy- positive Entropy- decreasing Free energy- negative
How will temperature affect the spontaneity of reaction with positive H and S?
A high temperature will make it spontaneous.
How will the temperature affect the spontaneity of a 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.
What happens to the entropy in the reaction I2s I2g?
Entropy increases in the reaction.
For which of reaction listed below will gibbs free energy always be positive?
Guys watch out the question, if your question end with positive then the answer will be An endothermic reaction that decreases in entropy. If the question end with negative then its An exothermic reaction that increases in entropy--APEX hope this help
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.
What happens to the entropy in the reaction I2 s I2 g?
Entropy increases in the reaction.
Do chemical reactions that increase entropy tend to occur spontaneously?
Reactions that increase the randomness. Reactions that have more moles of gas on the product side than the reactant side increase entropy. Also reactions that have a positive change in spontaneity and a negative enthalpy.
