Q1
For a reaction at constant temperature and pressure, which of the following is true?
ΔG = ΔH + TΔS
ΔG = ΔH - TΔS
ΔG = TΔS - ΔH
ΔG = ΔS - ΔH
Show Solution
Copy
The correct relationship at constant temperature and pressure is ΔG = ΔH - TΔS.

Q
Q: For a reaction at constant temperature and pressure, which of the following is true?
Solution:
The correct relationship at constant temperature and pressure is ΔG = ΔH - TΔS.
Steps: 6
Show Steps
Step 1: Understand that ΔG represents the change in Gibbs free energy of a system.
Step 2: Recognize that ΔH represents the change in enthalpy (total heat content) of the system.
Step 3: Identify that ΔS represents the change in entropy (disorder) of the system.
Step 4: Note that T is the absolute temperature in Kelvin.
Step 5: Remember that at constant temperature and pressure, the relationship between these quantities is given by the equation ΔG = ΔH - TΔS.
Step 6: Conclude that this equation helps determine if a reaction is spontaneous (ΔG < 0) or not (ΔG > 0).
