Question

Assertion (A) Critical temperature of CO2 is 304 K, it cannot be liquified above 304 K. Reason (R) At a certain temperature, Volume propto (1/ textpressure) (A) Both Assertion and Reason are true and Reason is the correct explanation of Assertion (B) Both Assertion and Reason are true but Reason is not the correct explanation of Assertion (C) Assertion is true but Reason is false (D) Both Assertion and Reason are false

Critical temperature of a gas may be defined as that temperature above which it cannot be liquefied however high pressure may be applied on the gas.
Hence,

C O_{2}

cannot be liquefied above its critical temperature
According to Boyle's law

p \propto \frac{1}{V}

or

V \propto \frac{1}{p} (

at constant

T

and

n

)

Q. Assertion (A) Critical temperature of CO2​ is 304K, it cannot be liquified above 304K. Reason (R) At a certain temperature, Volume ∝pressure1​

Both Assertion and Reason are true and Reason is the correct explanation of Assertion

Both Assertion and Reason are true but Reason is not the correct explanation of Assertion

Assertion is true but Reason is false

Both Assertion and Reason are false

Critical temperature of a gas may be defined as that temperature above which it cannot be liquefied however high pressure may be applied on the gas. Hence, CO2​ cannot be liquefied above its critical temperature According to Boyle's law p∝V1​ or V∝p1​( at constant T and n )

Q. Assertion (A) Critical temperature of $C O_{2}$ is $304 K$ , it cannot be liquified above $304 K$ .
Reason (R) At a certain temperature,
Volume $\propto \frac{1}{pressure}$
