Question

Critical temperature of CO is 304 K, it cannot be liquified above 304 K. At a certain temperature, $volume \propto\frac{1}{pressure}$

• A. If both assertion and reason are true and reason is the correct explanation of assertion.
• B. If both assertion and reason are true but reason is not the correct explanation of assertion.
• C. If assertion is true but reason is false.
• D. If both assertion and reason are false.

Answer 1

Answer: (B)

If both assertion and reason are true but reason is not the correct explanation of assertion.

Answer 2

Critical temperature of a gas may be defined as that temperature above which it cannot be liqufied however high pressure may be applied on the gas. Hence, CO cannot be liquified above its critical temperature. According to Boyle?? law $P\propto\frac{1}{V} or V \propto\frac{1}{P}$ (at constant T and n)
