Question: Which of the following conditions will lead to a negative ΔG?

Options:

Correct Answer: High temperature and high ΔS

Solution:

A high temperature and high ΔS will favor a negative ΔG, making the process spontaneous.

Which of the following conditions will lead to a negative ΔG?

Which of the following conditions will lead to a negative ΔG?

Step 1: Understand what ΔG means. ΔG is the change in free energy of a process.
Step 2: Know that a negative ΔG means the process is spontaneous, or can happen on its own.
Step 3: Learn about the equation ΔG = ΔH - TΔS, where ΔH is the change in enthalpy, T is the temperature in Kelvin, and ΔS is the change in entropy.
Step 4: Recognize that a high ΔS (increase in disorder) will make TΔS larger, which can help make ΔG negative.
Step 5: Realize that a high temperature (T) will also increase the TΔS term, further helping to make ΔG negative.
Step 6: Conclude that both high temperature and high ΔS are conditions that favor a negative ΔG.
