Explanation:
Entropy of a reaction ΔS∘rxn is the degree of disoderliness in a system. Gases generally have a higher degree of disorder compared to liquids. Hence for the reaction 2H2(g)+O2(g) ⟶ 2H2O(l), the entropy decreases sice the reactants are in the gaseous state and the products is in the liquid state of matter
Answer:
C
Explanation:
Because nothing is left at the end of the reaction.
Increase: volume, pressure, kinetic energy, gas particle collisions
Stays the same: number of moles of gas
