The standard entropy of acetylene is 201 J/mol.K
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.
delta S in terms of J/K is 149.58 J mol-1 K-1
The electron pair geometry of C2H2 is linear.
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.
The system becomes more random.
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.

C2H2 (acetylene) is a linear molecule.
yep!! C2H2 is a pure subsatnce

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.
The system becomes more random.
Delta S0 refers to the standard entropy change in a reaction, which is the measure of the dispersal of energy in a system or reaction at standard conditions (usually 25°C and 1 atm pressure). It represents the difference in entropy between the products and reactants in a reaction.
