Understanding Gibbs Free Energy and Spontaneity

What does a negative Delta G indicate about a process?

• The process is at equilibrium.

• The process is spontaneous.

• The process is non-spontaneous.

• The process is endothermic.

In which scenario is a process always non-spontaneous?

• Delta H is negative and Delta S is positive.

• Delta H is positive and Delta S is positive.

• Delta H is positive and Delta S is negative.

• Delta H is negative and Delta S is negative.

How does temperature affect the spontaneity of a process when both Delta H and Delta S are positive?

• The process is non-spontaneous at all temperatures.

• The process is spontaneous at high temperatures.

• The process is spontaneous at low temperatures.

• The process is non-spontaneous at high temperatures.

What happens to the spontaneity of a process when both Delta H and Delta S are negative and the temperature is low?

• The process reaches equilibrium.

• The process remains spontaneous.

• The process becomes non-spontaneous.

• The process becomes endothermic.

What tool can be used to predict spontaneity without calculations?

• A Delta G calculator.

• A temperature chart.

• A spontaneity chart.

• An enthalpy-entropy graph.
