For the relation, H(2)(g)+CO(2)(g) hArr ...

For the relation, `H_(2)(g)+CO_(2)(g) hArr H_(2)O(g)+CO(g)` show the equilibrium yield of the products is independent of pressure at constant temperature.

Text Solution

Verified by Experts

In the given reaction, no charge on volume takes place because the total number of moles of gaseous products is equal to the total number of moles of gaseous reactants (i.e., `Deltan=0`). So, according to Le chatelier's priciple, the change in presure will produce no effect on the equilibrium of the reaction as well as on the yield of products.
