What determine whether a reaction took place?
Whether a reaction took place is determined by the change in chemical composition, the formation of new substances, the release of energy or heat, and the color change or visible evidence of a chemical change. These factors indicate that a chemical reaction has occurred.
How does the entropy change in the reaction 2C3H6 (g) plus 9O (g) 6CO2(g)?
The entropy increase in this reaction.
What is the name and symbol of the single thermodynamic quantity which determines whether or not a reaction is spontaneous?
The name of the single thermodynamic quantity is Gibbs free energy (G). The symbol for Gibbs free energy is ΔG (delta G). The sign of ΔG determines whether a reaction is spontaneous (negative ΔG) or non-spontaneous (positive ΔG).
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."
How do you determine whether a reaction is spontaneous or non spontaneous?
A reaction is spontaneous if the Gibbs free energy change (ΔG) is negative. This means that the reaction can proceed without external energy input. In contrast, a reaction is nonspontaneous if ΔG is positive, meaning external energy is needed for the reaction to occur.
