At which temperature would a reaction with H -220 kJmol and S -0.05 kJ(mol K) be spontaneous?
To determine the temperature at which the reaction is spontaneous, we use the Gibbs free energy equation: ΔG = ΔH - TΔS. A reaction is spontaneous when ΔG < 0. Given ΔH = -220 kJ/mol and ΔS = -0.05 kJ/(mol K), we set up the equation: -220 kJ/mol - T(-0.05 kJ/(mol K)) < 0. Solving for T gives T > 4400 K, meaning the reaction is spontaneous at temperatures above 4400 K.
The equation G equals H-TS predicts that?
the Gibbs free energy (G) of a system is equal to the enthalpy (H) minus the temperature (T) multiplied by the entropy (S). This equation is used to determine whether a reaction is spontaneous (ΔG < 0) or non-spontaneous (ΔG > 0) at a given temperature.
At which temperature would a reaction with h -92 kj mol s-199 kj molk be spontaneous?
To determine the temperature at which the reaction becomes spontaneous, we can use the Gibbs free energy equation: ΔG = ΔH - TΔS. For a reaction to be spontaneous, ΔG must be less than 0. Given ΔH = -92 kJ/mol and ΔS = -199 kJ/(mol·K), we can set up the equation -92 kJ/mol - T(-199 kJ/(mol·K)) < 0. Solving for T gives T > 0.462 K, indicating that the reaction will be spontaneous at temperatures above this value.
What conditions are most likely to result in a spontaneous chemical reaction or process on the Gibbs free energy equation that is ΔG ΔH TΔS?
Conditions that are most likely to result in a spontaneous chemical reaction or process, based on the Gibbs free energy equation (ΔG = ΔH - TΔS), include when the change in enthalpy (ΔH) is negative (exothermic) and the change in entropy (ΔS) is positive. When ΔG is negative, the reaction will be spontaneous at the given temperature.

Which equation represents a spontaneous nuclear decay?

Using the Gibbs free energy equation what is the temperature range for which the oxidation of lead is spontaneous?
The reaction is spontaneous below 554.8/0.1975 K.
Use the gibbs free energy equation shown below to determine the temperature for which the decomposition of KClO4 is spontaneous?
To determine the temperature at which the decomposition of KClO4 is spontaneous, you need to know the Gibbs free energy change (∆G) for the reaction. If ∆G is negative, the reaction is spontaneous. Use the equation ∆G = ∆H - T∆S, where ∆H is the enthalpy change, ∆S is the entropy change, and T is the temperature in Kelvin. Set ∆G to 0 and solve for T to find the temperature at which the decomposition becomes spontaneous.
What is the Delta G prime equation used for in thermodynamics?
The Delta G prime equation is used in thermodynamics to calculate the standard Gibbs free energy change of a chemical reaction under standard conditions. It helps determine whether a reaction is spontaneous or non-spontaneous at a given temperature.
What is an example from real life where you would want to use a logarithmic equation?
If by "real life" you include the physical world, then you express the spontaneous decay of radioactivity in a sample with a logarithmic equation.
Using the Gibbs free energy equation what is the temperature in degrees celsius above which decompostion of KCIO4 is spontaneous?
-51 - -50.5
Use the Gibbs free energy equation shown below to determine the temperature range for which the decomposition of KCIO4 is spontaneous?
To determine the temperature range at which the decomposition of KClO4 is spontaneous, you would need the values for the standard Gibbs free energy change (ΔG°) and the equilibrium constant (K). By using the equation ΔG = -RTlnK and taking into account that ΔG = 0 for a reaction at equilibrium, you can rearrange to solve for the temperature range where decomposition is spontaneous.
What is the nuclear decay equation for uranium 235?
The equation for the alpha decay of 235U is: 92235U --> 90231Th + 24He representing the alpha particle as a helium nucleus. 235U also decays by spontaneous fission, but the results are somewhat unpredictable, so there is no standard equation.
At which temperature would a reaction with H -220 kJmol and S -0.05 kJ(mol K) be spontaneous?
To determine the temperature at which the reaction is spontaneous, we use the Gibbs free energy equation: ΔG = ΔH - TΔS. A reaction is spontaneous when ΔG < 0. Given ΔH = -220 kJ/mol and ΔS = -0.05 kJ/(mol K), we set up the equation: -220 kJ/mol - T(-0.05 kJ/(mol K)) < 0. Solving for T gives T > 4400 K, meaning the reaction is spontaneous at temperatures above 4400 K.
What is the equation that show white phosphorus undergo spontaneous combustion?
methane+oxygen-->carbon dioxide+waste CH4 O2 CO2 H2O
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.
The equation G equals H-TS predicts that?
the Gibbs free energy (G) of a system is equal to the enthalpy (H) minus the temperature (T) multiplied by the entropy (S). This equation is used to determine whether a reaction is spontaneous (ΔG < 0) or non-spontaneous (ΔG > 0) at a given temperature.
