Which thermodynamics law predicts correctly the degree of completion of a chemical reaction?

Question

Given $C_p = a + bT$
$a = 19.5$, $b = 0.042$, $n = 1$ mole
Temperature changes from $27^\circ C$ to $327^\circ C$.
Find $\Delta H$.

Answer 1

Step 1: Understand the thermodynamic principle governing reaction completion.
The second law of thermodynamics, concerning natural process direction and system disorder (entropy), determines the spontaneity and extent of chemical reactions.Step 2: Conclusion.
The second law of thermodynamics, specifically its effect on entropy change, dictates the extent to which a chemical reaction proceeds to completion. Final Answer: \[ \boxed{\text{Second law}} \]
