For a homogeneous reaction of order n, the unit of rate constant, k is ____(a) conc^n-1(b) (frac{conc^{-1}}{time} )(c) (frac{conc^{-1}}{time^{1-n}} )(d) (frac{conc^{1-n}}{time^{-1}} ) |

Answer» Correct option is (d) (frac{conc^{1-n}}{time^{-1}} ) To explain I would say: For any order n, (-rA) = kCA^n (frac{mol}{m^3×s} = k.(frac{mol}{m^3})^n ) Hence the unit of k is (frac{conc^{1-n}}{time^{-1}}. ) |
