Question

A mixture of 1 mole of  and 1 mole of CO is taken in a 10 litre container and heated to 725 K. At equilibrium, 40% of water by mass reacts with CO:

The equilibrium constant  for the reaction is  (Nearest integer)

Canvas Classes · Accepted Answer

Step 1 — ICE table (V = 10 L, initial moles: CO = 1, H₂O = 1):

40% of H₂O reacts  moles reacted = 0.4

| | CO | H₂O | CO₂ | H₂ |
|--|--|--|--|--|
| Initial | 1 | 1 | 0 | 0 |
| Change | −0.4 | −0.4 | +0.4 | +0.4 |
| Equil. | 0.6 | 0.6 | 0.4 | 0.4 |

Step 2 — Concentrations (V = 10 L):

Step 3 — Calculate :
