What conditions make G positive?

What conditions make G always negative?

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

What conditions make delta G always positive?

G is always positive when enthalpy increases and entropy decreases.

Under what conditions is G for a reaction always positive?

When H is positive and S is negative

What is a positive g force?

positive g foces is when a rollercoaster is expiriencing over 0 g forces in other words + g forces

How does gravity affect people riding roller coasters?

Gravity affect people on 6 axis. They are positive or negative x (lateral G's), positive or negative y (vertical G's), and positive or negative z (acceleration G's). Vertical G's When on a traditional coaster (rider is sitting in an upright facing forwards), vertical G's act on the rider up and down. When vertical G's are positive, they make the rider feel like he/she is being pushed into his/her seat. When negative vertical G's are present, they make the rider feel weightless, or even give people that "Stomach in your throat" feeling. Lateral G's When on a traditional coaster (rider is sitting in an upright position facing forwards), lateral G's act on the rider left and right. Positive lateral G's make the rider feel like he/she is being pushed to the right, and negative lateral G's make the rider feel like he/she is being pushed to the left. Acceleration G's When on a traditional coaster (rider is sitting in an upright position facing forwards), acceleration G's act on the rider forward and backwards. Positive acceleration G's make the rider feel like he/she is being pushed forwards (like quickly speeding up in a car; mainly felt on roller coasters with launches). Negative acceleration G's make the rider feel like he/she is being pulled backwards (mainly felt on the brakes of a roller coaster when decelerating)

When Under what conditions is G for a reaction always positive apex?

The Gibbs free energy change (ΔG) for a reaction is always positive when the reaction is non-spontaneous under the given conditions. This typically occurs at high temperatures for exothermic reactions (where ΔH is negative and ΔS is positive) or when the entropy change (ΔS) is negative while ΔH is positive. In such cases, the term TΔS is not large enough to overcome the positive ΔH, resulting in a positive ΔG.

What are the Three G?

The three types of g-forces are positive g, negative g and lateral g.

Will this entropy change by positive or negative N2 (g) 3h2 (g) 2nh3 (g)?

The reaction N2 (g) + 3H2 (g) → 2NH3 (g) shows an increase in entropy because it involves an increase in the number of gaseous molecules from 2 to 4. Therefore, the entropy change for this reaction is positive.

Is G for a reaction always positive?

No, the Gibbs free energy change (ΔG) for a reaction is not always positive. A negative ΔG indicates that a reaction is spontaneous and can proceed in the forward direction, while a positive ΔG means the reaction is non-spontaneous under standard conditions. When ΔG is zero, the system is at equilibrium, and no net change occurs. Thus, ΔG can be positive, negative, or zero, depending on the reaction conditions.

What are the three g forces?

The three types of g-forces are positive g, negative g and lateral g.

Is cellular respiration a negative or positive delta g?

Photosynthesis is a positive delta G as it produces more free energy than it uses. The overall result of the Gibbs equations shows that delta G is positive

Is there a difference between positive and negative g force?

Yes, there is a difference between positive and negative g-force. Positive g-force is the sensation of weight pressing down on you, like during takeoff in an airplane. Negative g-force is the sensation of weightlessness or forces pulling you away from an object, like in a roller coaster drop.
