Directions : In the following questions a statement of assertion (A) is followed by a statement of reason (R). Mark the correct choice as :
Assertion (A) : Smoking increases the carbon monoxide (CO) content in the blood which has greater affinity to haemoglobin than oxygen.
Reason (R) : CO forms a stable bond with haemoglobin and does not allow binding of oxygen. It reduces concentration of haem bound oxygen and causes oxygen deficiency in the body.
  • a)
    Both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion (A).
  • b)
    Assertion (A) is true but reason (R) is false
  • c)
    Both assertion (A) and reason (R) are true but reason (R) is not the correct explanation of assertion (A).
  • d)
    Assertion (A) is false but reason (R) is true.
Correct answer is option 'C'. Can you explain this answer?

Smoking increases the carbon monoxide (CO) content in the blood which has greater affinity to haemoglobin than oxygen. CO forms a stable bond with haemoglobin and does not allow binding of oxygen. It reduces concentration of haem bound oxygen and causes oxygen deficiency in the body. Smoking also damages alveolar walls, which reduces respiratory surface (emphysema).

Assertion and Reasoning

Assertion (A): Smoking increases the carbon monoxide (CO) content in the blood which has greater affinity to haemoglobin than oxygen.

Reasoning (R): CO forms a stable bond with haemoglobin and does not allow binding of oxygen. It reduces concentration of haem bound oxygen and causes oxygen deficiency in the body.

Explanation

The assertion is true because smoking increases the carbon monoxide (CO) content in the blood. When a person smokes, the CO enters the bloodstream and competes with oxygen to bind with haemoglobin. The CO has a greater affinity to haemoglobin than oxygen, so it forms a stable bond with haemoglobin.

The reasoning is also true because the CO-haemoglobin bond is stable and does not allow oxygen to bind with haemoglobin. This reduces the concentration of haem bound oxygen and causes oxygen deficiency in the body. The oxygen deficiency can lead to various health problems such as shortness of breath, fatigue, and even heart disease.

Therefore, both assertion (A) and reasoning (R) are true but reason (R) is not the correct explanation of assertion (A). The correct explanation for assertion (A) is that smoking increases the carbon monoxide (CO) content in the blood which has greater affinity to haemoglobin than oxygen.

Read the passage given below and answer the following questions:The rate of a reaction, which may also be called its velocity or speed, can be defined with relation to the concentration of any of the reacting substances, or to that of any product of the reaction. If the species chosen is a reactant which has a concentration c at time t the rate is - dc/dt, while the rate with reference to a product having a concentration x at time t is dx/dt. Any concentration units may be used for expressing the rate; thus, if moles per liter are employed for concentration and seconds for the time, the units for the rate are moles litre–1sec–1. For gas reactions pressure units are sometimes used in place of concentrations, so that legitimate units for the rate would be (mm. Hg) sec–1 and atm. sec–1 The order of a reaction concerns the dependence of the rate upon the concentrations of reacting substances; thus, if the rate is found experimentally to be proportional to the ath power of the concentration of one of the reactants A, to the both power of the concentration of a second reactant B, and so forth, via., rate = k CAα CAβ the over-all order of the reaction is simply n = α + β + ----- (2) Such a reaction is said to be of the αth order with respect to the substance A, the βth order with respect to B.In the following questions, a statement of Assertion followed by a statement of Reason is given. Choose the correct answer out of the following choices on the basis of the above passage.Assertion: Rate of reaction is a measure of change in concentration of reactant with respect to time.Reason: Rate of reaction is a measure of change in concentration of product with respect to time.
