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 EaE_a Equation used is log⁡\log\left(\frac{k_2}{k_1}\right)=\frac{E_a}{2.303 R}(1T1−1T2)\left(\frac{1}{T_1}-\frac{1}{T_2}\right) Hence EaE_a can be calculated if value of rate constant kk is known at two different temperatures T1T_1 and T2\mathrm{T}_2.
