A high temperature will make it spontaneous.
A reaction is considered spontaneous when it occurs without external intervention, typically at a specific temperature where the Gibbs free energy change (ΔG) is negative (ΔG < 0). The temperature at which a reaction becomes spontaneous can vary depending on the enthalpy (ΔH) and entropy (ΔS) changes associated with the reaction, as expressed in the Gibbs free energy equation: ΔG = ΔH - TΔS. If the entropy increases (ΔS > 0), the reaction may be spontaneous at lower temperatures, while if the enthalpy is favorable (ΔH < 0), it may be spontaneous at higher temperatures.
if H and S are both negative
the answer is 400
A reaction will be spontaneous at 298 K if the Gibbs free energy change (ΔG) for the reaction is negative. This means that the reaction will proceed in the forward direction without requiring an external input of energy. The equation ΔG = ΔH - TΔS can be used to determine if a reaction is spontaneous at a given temperature, where ΔH is the change in enthalpy and ΔS is the change in entropy.
No, an exothermic reaction is not always spontaneous. The spontaneity of a reaction depends on factors such as temperature, pressure, and the entropy change of the system.
The condition for a reaction to be spontaneous is ΔG < 0, where ΔG = ΔH - TΔS. At the temperature where ΔG becomes negative, the reaction will be spontaneous. You can calculate this temperature using the given values of ΔH and ΔS.
A high temperature will make it spontaneous.
A reaction will be spontaneous at a given temperature if the Gibbs free energy change (ΔG) is negative. ΔG = ΔH - TΔS. As ΔH = -92 kJ/mol and ΔS = -0.199 kJ/(mol.K), plug these values into the equation along with the temperature to solve for ΔG. If ΔG is negative, the reaction will be spontaneous at that temperature.

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.
if H and S are both negative
The reaction is spontaneous below 554.8/0.1975 K.
For the reaction to occur at room temperature, an external energy source must be provided to drive the reaction, and the reaction will absorb heat from the surroundings. The reaction is non-spontaneous because it does not occur naturally without intervention.
Yes, the reaction is exergonic and spontaneous.
A high temperature can make a nonspontaneous reaction spontaneous by providing enough energy to overcome the activation energy barrier, allowing the reaction to proceed. At low temperatures, the kinetic energy of the molecules may not be sufficient for them to react, but increasing the temperature can provide the necessary energy for the reaction to occur spontaneously.
