The correct difference between first and second – order reactions is that
View answer and explanation
Correct option: D
The half-life of a first order reaction does not depend on [A]0{\left[ \mathrm{A} \right]_\mathrm{0}}; the half-life of a second order reaction does
depend on [A]0{\left[ \mathrm{A} \right]_\mathrm{0}}
Option D (The half-life of a first order reaction does not depend on [A]0{\left[ \mathrm{A} \right]_\mathrm{0}}; the half-life of a second order reaction does depend on [A]0{\left[ \mathrm{A} \right]_\mathrm{0}}) is correct because this is the key difference in how half-life relates to initial concentration for first and second-order reactions.

If the reaction rate at a given temperature becomes slower then 1[A]2\frac{1}{{{{\left[ A \right]}^2}}} vs times are a straight line. Order of reaction is The rate constant (k′)\left( {k'} \right) of one of the reaction is found to be double that of the rate constant (k′′)\left( {k''} \right) of another reaction. Then the relationship between the corresponding activation energies of the two reaction (E′a  and  E′′a)\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.
