How form a spontaneous reaction 298 k?
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.
Is the reaction spontaneous or non-spontaneous at 298 k?
To determine if a reaction is spontaneous or non-spontaneous at 298 K, we can use the Gibbs free energy equation, ΔG = ΔH - TΔS. If ΔG is negative, the reaction is spontaneous; if ΔG is positive, it is non-spontaneous. The values of ΔH (enthalpy change) and ΔS (entropy change) must be known to evaluate the spontaneity at this temperature. Without specific values for ΔH and ΔS, we cannot definitively conclude the spontaneity.

What is the G for the following reaction under standard conditions (T 298 K) for the formation of NH4NO3(s)?
To determine the Gibbs free energy change (ΔG°) for the formation of NH4NO3(s) under standard conditions (298 K), you would typically refer to standard Gibbs free energy of formation values for the reactants and products involved in the reaction. The reaction is: [ \text{N}_2(g) + 2 \text{H}_2(g) + \text{O}_2(g) \rightarrow \text{NH}_4\text{NO}_3(s) ] By using the standard Gibbs free energies of formation (ΔGf°) for the reactants and products, you can calculate ΔG° using the equation: [ ΔG° = Σ(ΔGf° \text{ of products}) - Σ(ΔGf° \text{ of reactants}) ] Without the specific values, I cannot provide a numerical answer, but this is the method you would use to find ΔG° for the reaction.
Which equation represents an exothermic reaction at 298 K?
An exothermic reaction is one where heat is released to the surroundings. An example of an exothermic reaction equation at 298 K is: 2H2(g) + O2(g) -> 2H2O(l) + heat
Which compound is formed from its elements by an exothermic reaction at 298 K and 101.3 kPa?
Carbon dioxide (CO2) is formed from its elements (carbon and oxygen) by an exothermic reaction at 298 K and 101.3 kPa.
Which direction of the reaction is favored at 298 K?
At 298 K, the direction of a reaction is favored based on whether it is exothermic or endothermic. If the reaction is exothermic, it is favored in the direction that consumes heat, while for an endothermic reaction, it is favored in the direction that produces heat. The reaction will proceed in the direction that helps to minimize the overall energy of the system.
How form a spontaneous reaction 298 k?
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.
The enthalpy change for a chemical reaction exactly as it is written is what?
The enthalpy change for a chemical reaction exactly as it is written is known as the standard enthalpy of reaction (∆H°). It represents the amount of heat exchanged with the surroundings at constant pressure during a reaction happening under standard conditions (typically at 298 K and 1 atm pressure).
Which direction of the reaction is favored at 298 k room temperature use the reaction I2s I2g when H 62.4 kJ.mol-1 and S 0.145 kJ.mol-1.k-1?
The direction of the reaction is favored when the Gibbs free energy change (ΔG) is negative. You can calculate ΔG using the equation ΔG = ΔH - TΔS, where T is the temperature in Kelvin. At 298 K, the sign of ΔG will depend on the values of ΔH and ΔS. If ΔG < 0, the reaction is favored in the forward direction.

Calculate K at 298 K for the following reactions?
To calculate the equilibrium constant ( K ) at 298 K for a given reaction, you'll need the standard Gibbs free energy change (( \Delta G^\circ )) for the reaction, which can be determined from standard enthalpies and entropies of formation. The relationship between ( K ) and ( \Delta G^\circ ) is given by the equation ( \Delta G^\circ = -RT \ln K ), where ( R ) is the gas constant (8.314 J/mol·K) and ( T ) is the temperature in Kelvin. Rearranging this equation allows you to solve for ( K ) using the formula ( K = e^{-\Delta G^\circ / RT} ) once ( \Delta G^\circ ) is known.
