A gas can be liquified by applying pressure only when it is cooled below the critical temperature.
Critical temperature of

N H_{3}

is more than

C O_{2}

,
i.e.

T_{N H_{3}} = 405 K

and

T_{C O_{2}} = 304.1 K .

Hence,

N H_{3}

is liquified more easily than

C O_{2}

.
Therefore, Assertion and Reason are correct and Reason is the correct explanation of Assertion.
