Answer:3480s⁻¹
Explanation:We can solve the following problem using the Arrhenius equation.
Arrhenius equation is given by:
A=Pre-exponential factor or frequency factor
Ea=Activation energy
R=Ideal gas constant
T=Temperature
K=Rate constant
From the Arrhenius equation we can see that the rate constant K is related with the activation energy and frequency factor.
In the question we are given with the following data:
Ea=42KJ/mol=42x 1000 J/mol
A=8.0×10¹ per second
T=298K
R=8.314J/K mol
when we substitute these given values in Arrhenius equation
K=3480s⁻¹
The value of rate constant obtained is 3480s⁻¹.
Answer:
Rate law:
Integrated Rate Law:
Explanation:
We can see that the graph of time is linear compared to and the reaction is second order hence we get the rate law from .
The integrated rate law for second order is where A is .
The slope of the graph w.r.t time is equal to k. The slope of the graph from the table is 0.014 which is equal to k.
