Vedclass · Answer

(C) The Arrhenius equation is given by $k = A 	imes e^{-E_a / (RT)}$.Given that the activation energy $E_a = 0$.Substituting $E_a = 0$ into the equation,we get $k = A 	imes e^0 = A 	imes 1 = A$.This implies that the rate constant $k$ is equal to the frequency factor $A$ and is independent of temperature $T$.Since $k = 3.2 	imes 10^8 \ s^{-1}$ at $300 \ K$,the frequency factor $A$ is $3.2 	imes 10^8 \ s^{-1}$.Therefore,at $400 \ K$,the value of the frequency factor $A$ remains $3.2 	imes 10^8 \ s^{-1}$.

For a reaction $E_a = 0$ and $k = 3.2 \times 10^8 \ s^{-1}$ at $300 \ K$. The value of frequency factor at $400 \ K$ would be
