Question

How will equilibrium be affected in each of the following? Use "shift toward CO(g) + 3H2(g) <-> CHa(g) + H2O(g) + heat 22. The removal of CH4(g) 23. The addition of H2O(g)shift toward left 24. A decrease in temperature 25. A decrease in volume
please show your work

Answer 1

SOLUTION:

This problem makes use of Le Chatelier's principle which states that

"Change in any of the factors (concentration, pressure, volume, temperature etc.) that determine the equilibrium conditions of a system causes the equilibrium to shift in such a direction that minimizes the effect of the change."

This means

* If you remove product, the reaction makes more of the product.

* If you add product, the reaction tends to consume it.

* If you decrease temperature, the reaction generates more heat.

* If you decrease volume, the reaction goes towards the side having lesser no of gaseous particles thereby creating more volume.

Also, since heat is evolved in the given reaction, it is exothermic in nature.

CO(g) + 3 H2(g) - Chucg + H₂O(g) + heat 22. 23. The removal of Chu (9) shifts equilibrium forward (right). The addition of H₂O(g) shifts equilibrium backward (left). A decrease in temperature shifts equilibrium forward (right). A decrease in volume shifts equilibrium forward (right), 24. 25.
