(a). If both (A) and (R) are correct and (R) is the correct explanation of (A).
(b). If both (A) and (R) are correct but (R) is not the correct explanation of (A).
(c). If (A) is correct, but (R) is incorrect.
(d). If (A) is incorrect, but (R) is correct.
(e) if both (A) and (R) are incorrect.
Assertion (A): The amount CO in a gas sample can be determined by using the reaction
`I_(2)O_(5)+5COtoI_(2)+5CO_(2)`
IF gas sample liberates 127.g of 'I_(2)`. Then 70 g of CO were present in the sample.
Reason (R): CO gas is absorbed in ammonical CuCl solution.

The correct Answer is:
To solve the given assertion and reasoning question, we need to analyze both the assertion (A) and the reasoning (R) provided. ### Step-by-Step Solution: 1. **Understanding the Assertion (A)**: - The assertion states that the amount of CO in a gas sample can be determined using the reaction: \[ I_2O_5 + 5CO \rightarrow I_2 + 5CO_2 \] - It claims that if the gas sample liberates 127 g of \(I_2\), then 70 g of CO were present in the sample. 2. **Calculating Moles of Iodine (I2)**: - First, we need to calculate the number of moles of \(I_2\) liberated. - The molar mass of \(I_2\) (iodine) is 254 g/mol. - Moles of \(I_2\) can be calculated as: \[ \text{Moles of } I_2 = \frac{\text{Mass of } I_2}{\text{Molar mass of } I_2} = \frac{127 \text{ g}}{254 \text{ g/mol}} = 0.5 \text{ moles} \] 3. **Using Stoichiometry to Find Moles of CO**: - From the balanced equation, we see that 5 moles of CO produce 1 mole of \(I_2\). - Therefore, the moles of CO can be calculated as: \[ \text{Moles of } CO = 5 \times \text{Moles of } I_2 = 5 \times 0.5 = 2.5 \text{ moles} \] 4. **Calculating Mass of CO**: - The molar mass of CO (carbon monoxide) is \(12 + 16 = 28 \text{ g/mol}\). - The mass of CO can be calculated as: \[ \text{Mass of } CO = \text{Moles of } CO \times \text{Molar mass of } CO = 2.5 \text{ moles} \times 28 \text{ g/mol} = 70 \text{ g} \] 5. **Conclusion for Assertion (A)**: - The assertion is correct because the calculations confirm that if 127 g of \(I_2\) is liberated, then indeed 70 g of CO were present in the sample. 6. **Understanding the Reasoning (R)**: - The reasoning states that CO gas is absorbed in ammoniacal CuCl solution. - This statement is also correct because CO can react with ammoniacal CuCl to form a complex. 7. **Link Between Assertion and Reasoning**: - The reasoning provided does not explain the assertion directly. The assertion is based on stoichiometric calculations, while the reasoning discusses a different method of detecting CO. 8. **Final Evaluation**: - Since both the assertion (A) and reasoning (R) are correct, but the reasoning does not explain the assertion, the correct answer is: **(b)** If both (A) and (R) are correct but (R) is not the correct explanation of (A).
To solve the given assertion and reasoning question, we need to analyze both the assertion (A) and the reasoning (R) provided. ### Step-by-Step Solution: 1. **Understanding the Assertion (A)**: - The assertion states that the amount of CO in a gas sample can be determined using the reaction: \[ I_2O_5 + 5CO \rightarrow I_2 + 5CO_2 ...
