What is the standard entropy of H ion?
The standard molar entropy of an H+ ion at 25°C is approximately 0 J/mol-K. Since the H+ ion is a single charged particle with no internal degrees of freedom, its entropy is considered to be close to zero.
What is the standard molar entropy of solid sodium sulfate?
delta S in terms of J/K is 149.58 J mol-1 K-1
What is the electron pair geometry of C2H2?
The electron pair geometry of C2H2 is linear.
What statements are true for the standard entropy change during the conversion of ozone to oxygen?
The standard entropy change during the conversion of ozone to oxygen is positive, indicating an increase in disorder or randomness. This process is spontaneous at higher temperatures and non-spontaneous at lower temperatures.
What does delta S 0 mean in a reaction?
The system becomes more random.
What is the value for s reaction for the following reaction given the standard entropy values?
To calculate the standard entropy change (ΔS°) for a reaction, you need to use the formula: [ \Delta S° = \sum S°{\text{products}} - \sum S°{\text{reactants}} ] You would sum the standard entropy values of the products and subtract the sum of the standard entropy values of the reactants. If you provide the specific reaction and the standard entropy values, I can calculate it for you.
Is C2H2 plus H2 equal C2H4 spontenous written?
The standard free energy of formation of C2H2 is +209.20 kJ/mole, while that of C2H4 is +68.15 kJ/mole (and H2 zero since it is an element in its standard state). thus, at standard temperature and pressure (25 C, 1 Bar pressure) the reaction C2H2 + H2 -> C2H4 has a standard free energy change of -141 kJ/mole and thus "spontaneous" in that equilibrium constant >> 1.

The standard for entropy is defined by a perfectly ordered at?
The standard for entropy is defined by a perfectly ordered state, which is considered to have zero entropy. In thermodynamics, a perfectly ordered system has maximum predictability and minimal uncertainty, leading to no randomness or disorder. As systems become more disordered and energy is dispersed, entropy increases, reflecting the natural tendency towards disorder. This concept is crucial in understanding the second law of thermodynamics, which states that the total entropy of an isolated system can never decrease over time.
Cyclopropane or propylene has higher standard molar entropy?
Propylene due to the molecular structure.

How does the entropy change in the reaction 2C2H2(g) plus 5O2(g) 4CO2(g) plus 2H2O(l)?
In the reaction 2C2H2(g) + 5O2(g) → 4CO2(g) + 2H2O(l), the entropy decreases. This is because the reactants consist of gaseous molecules, which have higher entropy due to their greater freedom of movement, while the products include liquid water, which has lower entropy. Additionally, there is a reduction in the number of gas molecules from 7 (2 C2H2 + 5 O2) to 4 (4 CO2), further contributing to the decrease in disorder. Overall, the transition from gas to liquid and the reduction in the number of gas molecules results in a net decrease in entropy.
What is the entropy of water at 100 degree?
The entropy of water at 100 degrees Celsius (373.15 K) is approximately entropy can vary depending on pressure and phase. For liquid water at this temperature and standard pressure (1 atm), the molar entropy is about 70 J/(mol·K). If considering water in its gaseous state (steam) at the same temperature, the entropy is much higher, around 188 J/(mol·K).
