Consider the following plots of rate constant versus 1 T for four different reactions. which of the following orders is correct for the activation energies of these reactions?

Options

  1. AE c > E a > E d > E b
  2. BE b > E a > E d > E c
  3. CE a > E c > E d > E b
  4. DE b > E d > E c > E a

Correct answer

A. E c > E a > E d > E b

Step-by-step solution

As we know that Arhenious equation is given as K = A e - E a RT log ⁡ K = log ⁡ A - E a 2.303 R T Slope = - E a 2.303 RT Slope c > a > d > b . E c > E a > E d > E b
