The activation energy of a reaction can be determined from the slope of which of the following graphs?

Options

  1. Al n K v s . T
  2. Bl n K T v s . T
  3. Cl n K v s . 1 T
  4. DT ( ln     K ) vs . 1 T

Correct answer

C. l n K v s . 1 T

Step-by-step solution

As per Arrhenius equation K = A   e - E a R T ln K = In   A - E a R T Plot of ln K   v/s     1 T will give Slop = - E a R ∴ E a = - R ( s l o p e )
