Best answer
(a) For the given reaction,
`K_(P) = (p_(CO) xx p_(H_(2))^(3))/(p_(CH_(4)) xx p_(H_(2)O))`
(b) (i) According to Le Chatelier’s principle, the equilibrium will shift in the backward direction.
(ii) According to Le Chatelier’s principle, as the reaction is endothermic, the equilibrium will shift in the forward direction.
(iii) The equilibrium of the reaction is not affected by the presence of a catalyst. A catalyst only increases the rate of a reaction. Thus, equilibrium will be attained quickly.
