Which of the following reactions will get affected by increasing the pressure? Also, mention whether change will cause the reaction the reaction to go into forward of backward direction.
a. `COCl_(2)(g) hArr CO(g)+Cl_(2)(g)`
b. `CH_(4)(g)+2S_(2)(g) hArr CS_(2)(g)+2H_(2)S(g)`
c. `CO_(2)(g)+C(s) hArr 2CO(g)`
d. `2H_(2)(g)+CO(g) hArr CH_(3)OH(g)`
e. `CaCO_(3)(s) hArr CaO(s)+CO_(2)(g)`
f. `4NH_(3)(g)+5O_(2)(g) hArr 4NO(g)+6H_(2)O(g)`

Explanation
