Consider the 4 chemical reactions below. I. 2 H2O2(ℓ) → 2 H2O(ℓ) + O2(g)
II. N2(g) + 3 H2(g) → 2 NH3(g)
III. CaCO3(s) → CaO(s) + CO2(g)
IV. SO2(g) + H2O(ℓ) → H2SO3(aq)
For which reaction(s) will ∆S be negative?

the only liquid elements at standard temperature and pressure are bromine (br) and mercury (hg). although, elements caesium (cs), rubidium (rb), francium (fr) and gallium (ga) become liquid at or just above room temperature.

explanation:

the correct answer would be b) volume versus temperature, because they are also directly proportional.
