What can be said about a reaction with H 620 kJmol and S -0.46 kJ(molK)?
it can never be spontanious
What can be said about a reaction with delta H 62.4 kJmol and delta S 0.145 kJ(mol K)?
A reaction with a positive ΔH of 62.4 kJ/mol indicates that it is endothermic, absorbing heat from the surroundings. The positive ΔS of 0.145 kJ/(mol K) suggests that the reaction leads to an increase in entropy, favoring disorder. To determine the spontaneity at a given temperature, the Gibbs free energy change (ΔG = ΔH - TΔS) can be evaluated; if ΔG is negative, the reaction is spontaneous. At higher temperatures, the positive entropy change may make the reaction more favorable.
What can be said about the reaction?
What reaction to what? You didn't specify.
What can be said about the reaction 2NH3(g) N2(g) plus 3H2(g) H 92.4 kJmol?
The reaction 2NH3(g) ⇌ N2(g) + 3H2(g) has a ΔH of +92.4 kJ/mol, indicating that it is endothermic, meaning it absorbs heat from the surroundings. This suggests that increasing the temperature would favor the formation of products (N2 and H2) according to Le Chatelier's principle. Additionally, the reaction involves a decrease in the number of moles of gas, which may affect the equilibrium position depending on the pressure applied.
In a reaction If the energy of a product is less where does excess the energy go?
It is released as heat and/or light, the reaction is said to be exothermic.
What can be said about a reaction with H 620 kJmol and S -0.46 kJ(molK)?
it can never be spontanious
What can be said about a reaction with triangle H 620 kJmol and triangle S -046 kJ(mol.K)?
it is never spontaneous
What can be said about a reaction with H -890 kJmol and S -0.24 kJ(mol K)?
The reaction is exothermic because the enthalpy change is negative (-890 kJ/mol). The reaction may be spontaneous at low temperatures due to the negative entropy change (-0.24 kJ/(mol K)), which decreases the overall spontaneity of the reaction.
Ask us anythingUse the reaction I2(s) I2(g) H 62.4 kJmol S 0.145 kJ(molK) for question 10. What can be said about the reaction at 500 K?
At 500 K, the reaction will favour the formation of gaseous I2 since the positive change in enthalpy indicates the reaction is endothermic. The positive change in entropy suggests an increase in disorder, further favoring the formation of gaseous I2 at higher temperatures.

When is a reaction said to be unfavorable?
A reaction is said to be unfavorable when it requires more energy to occur than it releases.
What can be said about the reaction 2NH3(g) N2(g) plus 3H2(g) H 92.4 kJmol?
The reaction 2NH3(g) ⇌ N2(g) + 3H2(g) has a ΔH of +92.4 kJ/mol, indicating that it is endothermic, meaning it absorbs heat from the surroundings. This suggests that increasing the temperature would favor the formation of products (N2 and H2) according to Le Chatelier's principle. Additionally, the reaction involves a decrease in the number of moles of gas, which may affect the equilibrium position depending on the pressure applied.
When a chemical reaction and it's reverse occur at the same time and rate the reaction is said to be?
When the reaction reaches a point where reactants produced is equal to products produced the reaction is said to be in equilibrium. If that is what you afre talking about
What is it called if the temperature goes down in a reaction?
The reaction is said to be endothermic (draws heat in from the surroundings)
If oxygen is not present in a reaction it is said to be a what?
anaerob

They said Hi to Germany.
