Which of the following is not the characteristic of chemical equilibrium ?A. At equilibrium, the concentration of each of the reactants and the products becomes constant.B. At equilibrium, the rate of forward reaction becomes equal to the rate of backward reaction, and hence, the equilibrium is dynamic in mature.C. A chemical equilibrium can be estabilised only if none of the products is allowed to escape out separate out as a solid.D. Chemical equilibrium for the reversible reaction `N_(2)+3H_(2)hArr2NH_(3)` can be attained from forward direction only. |

Answer» Correct Answer - D Chemical equilibrium can be attained from either direction, i.e., from the direction of the reactants taking `N_(2)` and `H_(2)` and getting `NH_(3)` as well as from the direction of the products (taking `NH_(3)` and decomposing it into `N_(2)` and `H_(2)`). |
