Question 7: Thermodynamics & KTG

Question

Assertion : $$\mathrm{NH}_3$$ is liquidities more easily than $$\mathrm{CO}_2$$.
Reason : Critical temperature of $$\mathrm{NH}_3$$ is more than $$\mathrm{CO}_2$$.

Accepted Answer

A gas can be liquified by applying pressure only when it is cooled below critical temperature. Critical temperature of $$\mathrm{NH}_3$$ is more than $$\mathrm{CO}_2$$, i.e., $$T_{\mathrm{NH}_3}=405 \mathrm{~K}$$ and $$T_{\mathrm{CO}_2}=304.1 \mathrm{~K}$$.
Therefore, $$\mathrm{NH}_3$$ is liquified more easily than $$\mathrm{CO}_2$$. Hence, both assertion and reason are true and Reason is the correct explanation of assertion.

Answer

If both assertion and reason are true and reason is the correct explanation of assertion.

Answer

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

Answer

If assertion is true, but reason is false.

Answer

If both assertion and reason are false.
