Using "Le" Chateller's principle, predict the effect of
(i) decreasing the temperature and
(ii) increasing the pressure on each of the following equilibria:
(A) `N_(2)(g)+3H_(2)(g)hArr2NH_(3)(g)+"Heat"`
(B) `N_(2)(g)+O_(2)(g)hArr2NO(g)+"Heat"`
(C) `H_(2)O(g)+"Heat"hArrH_(2)(g)+(1)/(2)O_(2)(g)`
(D) `2CO(g)+O_(2)(g)hArr2CO_(2)(g)+"Heat"`
