Please define your terms.

I've had a shaky grasp on thermodynamics ever since taking P-Chem and University Physics at the same time, because the stupid conventions are different. Apparently chemists are interested in how much work you have to put in to the system to make the reaction go, and physicists (at least the ones who wrote the text we used) are interested in how much work you can get out of the system when the reaction does go, so they invert the signs. Try holding two different and incompatible versions of the same equations in your head at the same time, and you'll begin to understand my confusion.

If I'm remembering properly, in chemical terms a negativeenthalpy change indicates that the reaction is thermodynamically favored (i.e. exothermic).

What do Proton-Transfer reactions favor?

Proton-transfer reactions typically favor the formation of products that are more stable and have lower energy. This often involves the transfer of a proton to a site that is more basic or can better stabilize the resulting charge.


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

Gibbs free energy (G) becomes negative at a given enthalpy (H) and entropy (S) when the temperature (T) is sufficiently high, leading to a scenario where the entropy term (TΔS) outweighs the enthalpy term (ΔH) in the Gibbs free energy equation: G = ΔH - TΔS. Specifically, if ΔS is positive (indicating an increase in disorder) and ΔH is either negative or less positive than the product of T and ΔS, then G can be negative, promoting spontaneity in the reaction or process. This situation typically occurs in reactions that favor the formation of products with greater disorder at higher temperatures.


True or False A large positive value of entropy tends to favor products of a chemical reaction?

True, a large positive value of entropy tends to favor products of a chemical reaction. However, entropy can be offset by enthalpy; a large positive value of enthalpy tends to favor the reactants of a chemical reaction. The true measure to determine which side of a chemical reaction is favored is the change in Gibbs' free energy, which accounts for both entropy and enthalpy, as calculated by: Change in Gibbs = Change in Enthalpy - Temp in Kelvin * Change in Entropy A negative value of Gibbs free energy will always favour the products of a chemical reaction.


What would from a spontaneous reaction at 298 k?

A spontaneous reaction at 298 K occurs when the change in Gibbs free energy (ΔG) is negative. This means that the reaction can proceed without the input of external energy, often driven by enthalpy (ΔH) and entropy (ΔS) changes according to the relationship ΔG = ΔH - TΔS. If ΔS is positive, it can favor spontaneity even with a positive ΔH, as long as the temperature is sufficiently high. Conversely, a negative ΔH at lower temperatures also promotes spontaneity.


What is the active ingredient in oxoid AZT agar that is used on 'dirty site' swabs below the waist to inhibit gram negative intestinal flora and favor gram ve staph strep organisms?

The active ingredient in Oxoid AZT agar is aztreonam, a synthetic antibiotic that inhibits the growth of gram-negative bacteria while allowing gram-positive bacteria, such as staphylococci and streptococci, to grow. It is specifically designed to suppress the growth of gram-negative intestinal flora in order to isolate and identify gram-positive organisms on 'dirty site' swabs taken below the waist.

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.


Do endothermic reactions favor the formation of products or the presence of reactants?

Endothermic reactions favor the formation of products over the presence of reactants.

What is negative 3 plus positive 8?

When adding negative 3 and positive 8, we can think of it as moving 3 units to the left on the number line and then moving 8 units to the right. The net result is moving 5 units to the right. Therefore, negative 3 plus positive 8 is equal to positive 5.

What is true of spontaneous reactions when thinking about chemical systems?

Spontaneous reactions occur without needing external intervention to proceed, usually releasing energy in the process. These reactions tend to favor the formation of products and are generally driven by an increase in entropy. The direction of spontaneity can be determined by comparing the change in Gibbs free energy (ΔG) of the reaction to see if it is negative.


Is the cartoonist in favor of or against the embargo act?

To determine whether the cartoonist is in favor of or against the embargo act, we would need to analyze the imagery, symbols, and messages conveyed in the cartoon. If the cartoon depicts negative consequences or portrays the act as harmful, it likely indicates opposition. Conversely, if it highlights positive outcomes or supports the act’s intentions, it suggests favor. Without specific details about the cartoon, it's challenging to provide a definitive answer.
