Correctly Matched Pairs
The options provided relate to important concepts in thermodynamics and kinetics. Let's analyze each pair to identify which are correctly matched.
Arrhenius Equation
- The Arrhenius equation describes how the rate constant of a reaction depends on temperature and activation energy, not the variation of enthalpy with temperature. Therefore, this pair is incorrectly matched.
Kirchhoff Equation
- The Kirchhoff equation relates to the temperature dependence of reaction enthalpy changes, not the rate constant. Thus, this pair is also incorrectly matched.
Second Law of Thermodynamics
- This law states that the entropy of an isolated system tends to increase over time and will reach a maximum value at equilibrium. This correctly describes the essence of the second law, making this pair correctly matched.
Hess's Law of Constant Summation
- Hess's law asserts that the total enthalpy change for a chemical reaction is the same, regardless of the pathway taken. This means that enthalpy change is independent of the manner in which a reaction occurs, confirming that this pair is correctly matched.
Conclusion
- The correct matches are C (Second Law of Thermodynamics) and D (Hess's Law of Constant Summation). The inaccuracies in the other pairs clarify why they do not belong to the correct matches.
