Question

How will increase of pressure affect the equation? $C(s)+H_{2} O(g) C O(g)+H_{2}(g)$

• A. Shift in the forward direction
• B. Shift in the reverse direction
• C. Increase in the yield of hydrogen
• D. No effect

Answer 1

Answer: (B)

Shift in the reverse direction

Answer 2

$C(s)+H_{2} O(g) C O(g)+H_{2}(g)$
Here, $\Delta n>1$ Hence, decrease of pressure shifts the equilibrium in forward direction and increase of pressure shift the equilibrium in backward (reverse) direction.
