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

Options

  1. AIn K vs. T
  2. BIn K vs. 1 T
  3. CI n K T vs. 1 T
  4. DI n K T vs. T

Correct answer

B. In K vs. 1 T

Step-by-step solution

Arrhenius equation K = A . e - E a / R T l n K = l n A - E a R T So, activation energy of reaction can be determined from the slope of lnK vs 1 T . Using y = m x + c we can find the value of E a from slope value.
