Activation energy of any chemical reaction can be calculated if one knows the value of

Options

  1. Aprobability of collision
  2. Borientation of reactant molecules during collision
  3. Crate constant at two different temperatures
  4. Drate constant at standard temperature

Correct answer

C. rate constant at two different temperatures

Step-by-step solution

To calculate value of E_a Equation used is ( k₂ k₁ )= E_a 2.303 R ( 1 T₁ - 1 T₂ ) Hence E_a can be calculated if value of rate constant k is known at two different temperatures T₁ and T ₂ .
