Equilibrium constant (Kc’) = [N2]1/2[O2]/ [NO2] According to equations 1 and 2 –. Kc = (Kc’)2. It is clear that according to both the above equations different values of equilibrium constants are obtained, that is, the value of equilibrium constant depends on the equation of reaction.
WebWhere the concentration of $ C_6H_6 $ is 10 M and rate of the reaction is 5 M/sec. Hence, the rate constant of the chemical reaction is given as: \[ k = \dfrac{ 5 }{ 10 } \] \[ k = 0.5 sec^{ -1 } \] The unit of the rate constant can vary depending upon the number of reactants as the unit for the above-mentioned example is $ sec^{-1}$.
