1.	Dihydrogen gas is obtained frjom natural gas by partial oxidation with steam as per the endothermic reaction : CH_(4) (g) + H_(2) O (g) hArr CO (g) + 3 H_(2) (g) (a) Write an expression for k_(p) for the above reaction. (b) How will the value of K_(p) and composition of the equilibrium mixture be affected by (i) increasing the pressure (ii) using a catalyst ?
Answer» <P> SOLUTION :(a) ` K_(p) = (p_(CO)xx p_(H_(2))^(3))/(p_(CH_(4)) xx p_(H_(2)O` (b) (i) By Le Chatelie's principle , equilibrium will shifts in the backward direction (as ` n_(r) lt n_(p))`(II) As the given reaction is endothermic , by Le Chatelier's principle , equilibrium will shift in the forward direction. (III) Equilibrium composition will not be disturbed but equilibrium will be attained quickly .
