In the equation ΔG = ΔH - TΔS, ΔH represents the change in enthalpy, which corresponds to the heat content of a system during a process at constant pressure. It indicates whether a reaction is exothermic (release of heat, ΔH < 0) or endothermic (absorption of heat, ΔH > 0). ΔG, the change in Gibbs free energy, determines the spontaneity of a process, while TΔS accounts for the change in entropy, reflecting the disorder of the system. Together, these thermodynamic quantities help predict whether a reaction will occur spontaneously.

What equation is a balanced equation that includes the physical states of all reactants and products and the enthalpy change?

A balanced equation that includes the physical states of all reactants and products, along with the enthalpy change, is typically formatted as follows: [ \text{Reactants (s, l, g, aq)} \rightarrow \text{Products (s, l, g, aq)} \quad \Delta H = \text{value (kJ/mol)} ] For example, for the combustion of methane, the equation can be written as: [ \text{CH}_4(g) + 2 \text{O}_2(g) \rightarrow \text{CO}_2(g) + 2 \text{H}_2\text{O}(l) \quad \Delta H = -890 , \text{kJ/mol} ] This indicates the states of matter and the energy change associated with the reaction.


At which temperature would a reaction with h-92 kjmol s-0.199 kj(molk) be spontaneous?

To determine whether the reaction is spontaneous, we can use the Gibbs free energy equation, ( \Delta G = \Delta H - T\Delta S ). For the reaction to be spontaneous, ( \Delta G ) must be less than 0. Given ( \Delta H = -92 , \text{kJ/mol} ) and ( \Delta S = -0.199 , \text{kJ/(mol K)} ), we can set up the inequality ( -92 , \text{kJ/mol} - T(-0.199 , \text{kJ/(mol K)}) &lt; 0 ). Solving this will give the temperature threshold above which the reaction becomes spontaneous.


What determine whether a reaction took place?

Use the following equation: delta G = delta H - T*deltaS. A reaction is spontaneous if delta G is negative. A reaction will always be spontaneous (under any temperature) only if the change in enthalpy (delta H) is negative and the change in entropy (delta S) is positive. If this is not the case, the reaction will only be spontaneous (negative delta G) for a range of temperatures (or could be always non-spontaneous)
