One mole of $N_{2} (g)$ is taken in $1$ litre empty container fitted with a movable piston at $300 K .$ If it is heated to $1200 K$ at constant pressure then match the change (List $- II$ ) in parameters (List $- I$ ) of gas as compared to initial state $&$ select the correct code.

List $- I$ (Parameter)		List $- II$ (Change)
$(P)$	$Z_{1}$ (number of collision made by a molecule per unit time)	$(1)$	$\frac{1}{8}$
$(Q)$	$Z_{11}$ (collision frequency)	$(2)$	$2$
$(R)$	$λ$ (mean free path)	$(3)$	$\frac{1}{2}$
$(S)$	$U$ (root mean square speed)	$(4)$	$4$
