If a reaction follows the Arrhenius equation, the plot k vs 1 ( RT ) gives straight line with a gradient (- y ) unit. The energy required to activate the reactant is:

Options

  1. Ay / R unit
  2. By unit
  3. CyR unit
  4. D-y unit

Correct answer

B. y unit

Step-by-step solution

From Arrhenius equation, k=A e^ -E_ n / R T k= A- E_ a R T slope =-y (given) -y=-E_ s E _ a =y
