1 mole each of `N_2(g)` and `O_2(g)` are introduced in a 1L evacuated vessel at 523 K and equilibrium `N_2(g)+O_(2)ghArr2NO(g)` is established.The concentration of `NO(g)` at equilibrium :A. Changes on changing volume of vesselB. Changes on changing temperatureC. Changes on changing pressureD. Remains same even when a platinum gauze is introduced to catalyse the reaction |

Answer» Correct Answer - A,B,C,D `N_2(g)+O_2(g)hArr 2NO(g)` (A)For changing pressure volume has to be changed, though number of moles of NO(g) do not get changed but its concentration will get changed. (B)Temperature change will change `K_P` and hence concentration. ( C)Volume change will change concentration, not the number of moles. (D)Catalyst does not change equilibrium concentrations. |
