Question

3. The chlorine monoxide (CIO) demonstrated three bimolecular self-reactions CIO(g) - CIO(g) → Ch(9) O(g) CIO(g) CIO(g) → C (9) + CIOO(g) CIO(g) + CIO(g) > Cl(g) Ocio(9) The following table provides the Arrhenius parameters for these reaction Reaction Pre-Exponential Factor (M's!) Activation Energy (kJ mol') 6.08 x 108 114 178 x 1010 20.4 2.11 x 102 132 Which of the following is TRUE about of enthalpy activation Hand entropy of activation AS: A) in reaction the enthalpy of activation is the lowest, while its entropy of activation is the highest observed value The enthalpy of activation is the lowest in reaction "T and the entropy of activation is the highest in reaction" the enthalpy of activation is the lowest while its of activation is ther ighest observed value In reaction the rithalpy of activation is the lowest, while its entropy of activation is the highest observed value The enthalpy of activations the highest in reaction and the entropy of activation is the lowest in teaction |

Answer 1

Enthalpy of activation and entropy of activation is predicted by Eyring equation which is written below entropy of activation is determined through Pre - exponential factor ( A ) higher the value of A more is entropy of activation and enthalpy of activation is calculated by exponential term according to given data entropy of activation will be greater for reaction 2 and enthalpy of activation will be lowest for reaction 1 so correct answer is option( B )
