Answer:

Explanation:
You can calculate the entropy change of a reaction by using the standard molar entropies of reactants and products.
The formula is

The equation for the reaction is
                         C₂H₄(g) + 3O₂(g) ⟶ 2CO₂(g) + 2H₂O(ℓ)
ΔS°/J·K⁻¹mol⁻¹   219.5      205.0         213.6         69.9

 
        
             
        
        
        
Start by adding the numbers then divide
        
             
        
        
        
They have a mass for the particles
There are no totally elastic collisions 
There are intermolecular forces
