The correct Answer is:
To analyze the assertion and reason provided in the question, we can break down the solution into clear steps: ### Step 1: Understand the Assertion The assertion states that "The ratio of volume of gaseous reactants and products is in agreement with their molar ratio." This is based on Avogadro's Law, which states that equal volumes of gases at the same temperature and pressure contain an equal number of moles. Therefore, the ratio of volumes of gaseous reactants and products will indeed reflect their molar ratio. ### Step 2: Analyze the Reason The reason provided states that "Volume of a gas is inversely proportional to the number of moles of a gas." This statement is incorrect. According to the ideal gas law (PV = nRT), volume is directly proportional to the number of moles when temperature and pressure are constant. Therefore, if the number of moles increases, the volume also increases, not decreases. ### Step 3: Conclusion Since the assertion is true and the reason is false, we conclude that the assertion stands independently as a correct statement, while the reason does not support it. ### Final Answer The assertion is true, and the reason is false. Therefore, the correct option is that the assertion is correct, but the reason is incorrect. ---
