प्रश्न
Two moles of NH3 are introduced into the one-litre flask in which it dissociates at high temperature as follows: 2NH3(g) ⇌ N2(g) + 3H2(g). Determine Kc, if at equilibrium 1 mole of NH3 remains.
उत्तर
2NH3 ⇌ N2 + 3H2
Initial conc. 2 mol L-1 0 0
At equilibrium 1 mol L-1 0.5 mol L-1 1.5 mol L-1
Now. `K_c = ([N_2][H_2]^3)/([NH_3]^2) = ([0.5][1.5]^2)/([1.0]^2)`
`K_c = 1.6875 " mol"^2 L^-2`
