5. What are the important equations in Class 12 Chapter 4 of Chemistry?

Chemical Kinetics is a new branch of Chemistry for Class 12 students which deals with rates of chemical reactions. This brings in a lot of concepts and equations because the number of reactions and the problems based on them is numerous. So, some of the important equations are:

  • Instantaneous Rate=dx/dt

  • Average Rate = ∆x/∆t

  • Rate = k* [A]^x [B]^y

  • K=[Ro]-[R]/t

  • t1⁄2 =[Ro]/2k

  • Arrhenius equation, k=Ae^(-Ea)/RT

  • Log(k1/k2) = Ea*(T2-T1)/2.303R*T1T2.
