Answer:
The true statement is: Spontaneous reactions tend to lead to higher entropy.
Explanation:
The spontaneity of a reaction is linked to the value of Gibbs free energy (ΔG°). The more negative is this value, the more spontaneous is a reaction. At the same time, Gibbs free energy depends on enthalpy (ΔH°) and entropy (ΔS°), according to the following expression:
ΔG° = ΔH° - T.ΔS°
We can see that higher entropies (higher ΔS°) lead to more negative ΔG°, thus, more spontaneous reactions.
<span>The balloons volume as it
rises increases because at higher altitude external pressure is lower, so the
air molecules inside the balloons tends to expand more to attain mechanical
equilibrium, where the external pressure and internal pressure are equal. Unlike
when the balloon is on the ground, external pressure is great so the gas
molecule cannot push the walls of the balloon so it is like underinflated.</span>
