A chemical reaction has a positive H value and a positive S value Under what conditions is the reaction spontaneous?
The spontaneity of a reaction is determined by the sign of the Gibbs free energy (ΔG). If both enthalpy (H) and entropy (S) are positive, the reaction can be spontaneous at high temperatures where the TΔS term outweighs the positive ΔH term, resulting in a negative ΔG. This means the reaction will be spontaneous at elevated temperatures.
What is the value of G for a reaction that is spontaneous?
The value of Gibbs free energy (G) for a spontaneous reaction is negative, indicating that the reaction is thermodynamically favorable and can proceed without external intervention. This negative value indicates that the products are at a lower energy state than the reactants, driving the reaction forward.
A chemical reaction has a positive ΔH value and a positive ΔS value Under what conditions is the reaction spontaneous?
The reaction will be spontaneous at high temperatures (T) where TΔS > ΔH, according to Gibbs free energy equation, ΔG = ΔH - TΔS. At high enough temperatures, the TΔS term can outweigh the positive ΔH term, leading to a negative ΔG value and a spontaneous reaction.
What value should the heat of the reaction have in a spontaneous reaction?
It can be + or - depending on the value of the entropy (∆S). Recall, that ∆G = ∆H - T∆S and for a spontaneous reaction, ∆G must be negative, so you can see how this will depend on the values and signs of both enthalpy and entropy.
What does a negative value for the standard potential indicate?
the negative value for a standard potential indicates that the reaction is not spontaneous.
What is the difference between a reaction that happens spontaneously and a reaction that doesn't?
The difference can be clarified by entropy (the second rule of thermodynamics).The reaction is more spontaneous with higher entropy, for the reactions that occur spontaneously the entropy is higher than for the ones that do not.
What is a negative Gibbs free-energy value an indication of?
A negative Gibbs free-energy value indicates that a reaction is spontaneous, meaning it can proceed without requiring external energy input. It suggests that the products of the reaction are more stable than the reactants at the given conditions.
What is true about the numerical value of the Gibbs free-energy change for a spontaneous reaction?
For a spontaneous reaction, the numerical value of the Gibbs free-energy change (ΔG) is negative, indicating that the reaction is energetically favorable and will proceed in the forward direction. This negative ΔG means that the system is releasing energy and increasing in entropy during the reaction.
How do you know if a reaction is spontanious?
A reaction is spontaneous if it occurs without any external intervention and leads to a decrease in Gibbs free energy. This is driven by the system's tendency to increase entropy and decrease in internal energy. Mathematically, a reaction is spontaneous if ΔG < 0 at constant temperature and pressure.
Is greater 11.320 or 11.32?
Neither are greater, they are of equal value.
Which is greater 0.33 or 0.330?
Neither is greater. They are equal. Zeros on the end of a decimal don't affect the value.
