The correct Answer is:
To solve the question regarding the assertion and reason statements, we will analyze each statement step by step. ### Step-by-Step Solution: 1. **Understanding the Assertion**: - The assertion states that "The equilibrium constant of a reaction increases if temperature is increased." - The equilibrium constant (K) is influenced by temperature, but whether it increases or decreases depends on the nature of the reaction (exothermic or endothermic). 2. **Analyzing the Reaction Type**: - For an **endothermic reaction** (where heat is absorbed), increasing the temperature will shift the equilibrium to the right, thus increasing the equilibrium constant (K). - For an **exothermic reaction** (where heat is released), increasing the temperature will shift the equilibrium to the left, thus decreasing the equilibrium constant (K). 3. **Conclusion on Assertion**: - Since the assertion does not specify the type of reaction, we cannot definitively say that the equilibrium constant always increases with temperature. Therefore, the assertion is **incorrect**. 4. **Understanding the Reason**: - The reason states that "The forward reaction becomes faster with an increase of temperature." - Generally, according to the Arrhenius equation, increasing the temperature increases the kinetic energy of the molecules, which typically results in an increased rate of reaction. 5. **Conclusion on Reason**: - While it is generally true that increasing temperature increases the rate of reaction, this statement does not consider the specific nature of the reaction (exothermic vs. endothermic). However, in most cases, it can be considered **correct**. 6. **Final Evaluation**: - Since the assertion is incorrect and the reason is generally correct but not universally applicable, the overall conclusion is that both statements are not aligned correctly. Thus, the correct answer is **D: Both Assertion and Reason are false**.
