The rate constant

\left( {k'} \right)

of one of the reaction is found to be double that of the rate constant

\left( {k''} \right)

of another reaction. Then the relationship between the corresponding activation energies of the two reaction

\left( {{{E'}_a}\;\mathrm{and}\;{{E''}_a}} \right)

can be represented as

View answer and explanation

Correct option: D

{{E'}_a} < {{E''}_a}

Option D (

{{E'}_a} < {{E''}_a}

) is correct because a higher rate constant implies a lower activation energy, according to the Arrhenius equation.
