Which of the following reactions will get affected by increasing the pressure? Also mention whether chasnge will cause the reaction to go into forward or backward direction.
(i) `COCl_(2)(g)hArrCO(g)+Cl_(2)(g)`
(ii) `CH_(4)(g)+2S_(2)(g)hArrCS_(2)(g)+2H_(2)S(g)`
(iii) `CO_(2)(g)+C(s)hArr2CO(g)`
(iv) `4NH_(3)+(g)+5O_(2)(g)hArr4NO(g)+6H_(2)O(g)`

Explanation

`CO_(2_((g)))+C_((s)) hArr 2CO_((g))` (affected by pressure)
