Chemistry In Everyday Life

Step 1: Analyze each relation. 1. Relation (A):
This is incorrect. The correct relation is (for constant pressure). 2. Relation (B):
This is correct. It represents the first law of thermodynamics, where is the change in internal energy, is heat, and is work. 3. Relation (C):
This is correct. It represents the second law of thermodynamics, stating that the total entropy of a system and its surroundings always increases or remains constant for a spontaneous process. 4. Relation (D):
This is correct. It represents the Gibbs free energy equation, where is the change in Gibbs free energy, is the change in enthalpy, is temperature, and is the change in entropy.
Step 2: Determine the incorrect relation.
The incorrect relation is (A) .
