Answer 1

Answer:

b

Explanation:

Answer 2

G is always positive when enthalpy increases and entropy decreases.

What determines if a reaction is spontaneous?

The temperature can be the deciding factor in spontaneity when the enthalpy and entropy terms have opposite signs: If ΔH is negative, and –TΔS positive, the reaction will be spontaneous at low temperatures (decreasing the magnitude of the entropy term).

Why is negative Gibbs free energy spontaneous?

Where ΔH is the enthalpy change (the heat of the reaction) and ΔS is the change in entropy. If the free energy is negative, we are looking at changes in enthalpy and entropy that favor the process and it occurs spontaneously.
