1.	Dihydrogen gas is obtained from natural gas by partial oxidation with steam as per following endothermic reaction: CH_(4)(g) +H_(2)O(g) hArr CO(g) hArr CO(g) + 3H_(2)(g) (a) Write an expression for K_p for the above reaction. (b) How will the values of K_p and composition of equilibrium mixture bge affected by (i) increasing the pressure (ii) increasing the temperature (iii) using a catalyst ?
Answer» Solution :(a) `K_(P)=([P_(co)][p_(H_2)]^3)/([p_(CH_4)][P_(H_2O)])` (b) (i) VALUE of `K_p` will not CHANGE , EQUILIBRIUM will shif in BACKWARD direction. (ii) value of `K_p` will increase and reaction will proceed in forward direction. (iii) no effect.
