For a reaction with a positive enthalpy change (ΔH > 0) and a positive entropy change (ΔS > 0), the spontaneity is influenced by temperature through the Gibbs free energy equation: ΔG = ΔH - TΔS. As temperature increases, the TΔS term becomes larger, which can make ΔG more negative, thereby favoring spontaneity. Therefore, at higher temperatures, the reaction is more likely to be spontaneous, while at lower temperatures, it may not be spontaneous.

Why is triangle symbol used in chemical reaction?

A triangle symbol in a chemical reaction formula means that there is heat supplied to the reaction. The triangle is typically placed above the arrow between reactants and products. Sometimes the word "heat" is also written above the arrow.


What does a positive triangle h for a molecule mean?

I'm not sure exactly what triangle you are talking about, but if it is in an equation, it means "change in" whatever variable it is next to (and the proper word for it is "delta"). In the specific case where it's written under or over the arrow in a reaction, it means "heat" as in "you have to heat this in order to make the reaction happen." A point-down triangle is pronounced "del" and is somewhat different mathematically, but it's still related to the concept of change. A triangle can also be an instrument in chemistry that holds a crucible in labs. ok well i think what your asking, is what the triangle above the arrow in an equation means. I'm pretty sure it means heat. So if there is a triangle above the arrow in a reaction equation it means that heat was used to make this reaction occurs. hope that helps

Is a symbol which stands for the value equal to the entirely enthalpy minus the temperature times enthropy . It can be used to determine if a reaction will take place?

The change in Gibbs Free Energy (∆Gº) predicts if a reaction is spontaneous or not. The equation for this is ∆G = ∆H - T∆S where ∆H is the change in enthalpy, T is temperature in Kelvin, and ∆S in change in entropy.

Can a triangle have a positive side?

Yes, the sides are lengths and those are positive. Even a degenerate triangle which is 3 collinear points joined by line segments has positive sides. (it's angles add up to 180 and its area is zero, by the way but the usual triangle lies in a unique plane while the degenerate one does not)
