What conditions make delta G always positive?

G is always positive when enthalpy increases and entropy decreases.


What does delta S 0 mean in a reaction?

The system becomes more random.


What does the delta s 0 mean in a reaction?

The delta S^0 in a reaction refers to the standard entropy change. It represents the difference in entropy between the products and reactants at standard conditions (1 atm and 298 K). A positive delta S^0 indicates an increase in disorder or randomness, while a negative delta S^0 indicates a decrease in disorder.


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."


Can delta s be negative Entropy?

yes


What is delta S in the equation delta G delta H-T delta S?

Delta S represents the change in entropy of a system. In the equation delta G = delta H - T delta S, it is used to determine the contribution of entropy to the overall change in Gibbs free energy. A negative delta S value suggests a decrease in the disorder of a system.


What conditions make G always negative?

G is always negative when H is negative and S is positive.


What condition is G for a reaction always positive?

When H and S are both positive


Is prime number positive or negative number?

Its a positive number(s)


What could make delta G become negative at a given enthalpy and entropy?

For delta G to become negative at a given enthalpy and entropy, the process must be spontaneous. This can happen when the increase in entropy is large enough to overcome the positive enthalpy, leading to a negative overall Gibbs free energy. This typically occurs at higher temperatures where entropy effects dominate.


A chemical reaction that has a positive ΔG is correctly described as?

This is a nonspontaneous reaction, which means that it is reactant-favored. According to the second law of thermodynamics, product-favored reactions must have a negative delta G.It can also be described as an endergonic reaction - that is a chemical reaction in which the standard change in free energy is positive, and energy is absorbed.


Is S epidermidis gram negative or gram positive?

S. epidermidis is a Gram-positive bacterium. It appears purple when subjected to a Gram stain due to its thick peptidoglycan layer in the cell wall.
