For the homogeneous reaction, NH ₃+ OCl ⁻ N ₂ H ₄+ Cl ⁻ the equilibrium constant K_c has the units

Options

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

Correct answer

B. (conc.) ⁺¹

Step-by-step solution

For the given reaction, n_g=n_p-n_r (where, n_p= number of moles of gaseous products and n_r= number of moles of gaseous reactants). n_g=(6+4)-(4+5)=+1 Units of K_c= (concentration) ^ n_g =( concentration )⁺¹
