Question
An industrial fuel, ′water gas′ , which consists of a mixture of H2 and CO can be made by passing steam over red-hot carbon. The reaction is
C(s) + H2O(g) ⇋ CO(g) + H2(g), DH = +131 kJ
The yield of CO and H2 at equilibrium would be shifted to the product side by :
C(s) + H2O(g) ⇋ CO(g) + H2(g), DH = +131 kJ
The yield of CO and H2 at equilibrium would be shifted to the product side by :
Options
A.raising the relative pressure of the steam
B.adding hot carbon
C.raising the temperature
D.reducing the volume of the system
Solution
Addition of solids have no effect on equilibrium and temperature favours endothermic direction while increasing pressure will shift equilibrium in backward direction as ᐃng is + ve.
