For the homogeneous reaction, NH3+OCl−⟶N2H4+Cl−\mathrm{NH}_3+\mathrm{OCl}^{-} \longrightarrow \mathrm{N}_2 \mathrm{H}_4+\mathrm{Cl}^{-} the equilibrium constant KcK_c has the units

Options

  1. A(conc.) +10{ }^{+10}
  2. B(conc.) +1{ }^{+1}
  3. C(conc.) −1{ }^{-1}
  4. Dit is dimensionless

Correct answer

B. (conc.) +1{ }^{+1}

Step-by-step solution

For the given reaction, Δng=np−nr\Delta n_g=n_p-n_r (where, np=n_p= number of moles of gaseous products and nr=n_r= number of moles of gaseous reactants). Δng=(6+4)−(4+5)=+1\Delta n_g=(6+4)-(4+5)=+1 Units of Kc=K_c= (concentration) Δng=( concentration )+1{ }^{\Delta n_g} =(\text{ concentration })^{+1}
