Match the following `:`
List-I List-II
(P) `N_(2) (g) + 3H_(2) ( g) rarr 2NH_(3)(g)` (1) Increase in volume favours forward reaction
( Q ) ` 2NO(g) rarr N_(2)(g) + O_(2)(g)` ( 2) Increase in pressure accelerate the forward reaction
( R ) `CaCO_(3) (s) rarr CaO(s) + CO_(2)(g)` (3) `K_(p) = P _("total")`
( S) `PCl_(5)(g) rarr PCl_(3)_(g) + Cl_(2)(g)` (4) At constant volume introduction of inert gas, has no effect.
Codes `:`

Options

A. `{:(P,Q,R,S),(2,4,3,1):}`
B. `{:(P,Q,R,S),(2,3,1,4):}`
C. `{:(P,Q,R,S),(3,1,4,2):}`
D. `{:(P,Q,R,S),(4,3,1,2):}`

Answer

A

Explanation

Le-chateliers principle is applicable and for ( R ) `P_("total") = P_(CO_(2))`, which is equal to `K_(p)` for the given reaction.
