Assertion Standard boiling point of a liquid is slightly higher than the normal boiling point. Reason I bar pressure is slightly less than I atm pressure.

Options

  1. AAssertion and Reason are correct statements and reason is the correct explanation for Assertion.
  2. BAssertion and Reason are correct statements and Reason is not the explanation for Assertion.
  3. CAssertion is correct, Reason is incorrect.
  4. DAssertion is incorrect, Reason is correct.

Correct answer

D. Assertion is incorrect, Reason is correct.

Step-by-step solution

Assertion It is incorrect because standard boiling point (b.p. at 1 bar pressure) of a liquid is slightly lower than the normal boiling point (b.p. at (1 ~atm ) pressure). It is because 1 bar pressure is slightly lower than (1 ~atm ) pressure. Reason It is correct because (1 ~atm =1.01325 ) bar. Since, Assertion is incorrect, Reason is correct.
