Which statement is not correct?

View answer and explanation

Correct option: B

For exothermic reactions, heat of reaction is more than energy of activation

Option B (For exothermic reactions, heat of reaction is more than energy of activation) is correct because for exothermic reactions, the heat of reaction is negative, and its magnitude is typically less than the activation energy.

If the reaction rate at a given temperature becomes slower then

\frac{1}{{{{\left[ A \right]}^2}}}

vs times are a straight line. Order of reaction is 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 Acid hydrolysis of sucrose is a Order of radioactive disintegration reaction is Temperature coefficient of a reaction is 2. When temperature is increased from

30^\circ C\;to\;100^\circ C

, rate of the reaction increases by
